LONDON -- British police on Tuesday named the third London Bridge attacker as an Italian national of Moroccan descent, and Italian officials said they had passed on their concerns about him to British intelligence officials last year.

Police said 22-year-old Youssef Zaghba lived in east London and that his family has been notified, adding that he had not been considered to be a "subject of interest" to either police or the intelligence services.
The other two attackers were named Monday as Khuram Shazad Butt and Rachid Redouane.
The three, who were wearing fake suicide vests, were shot dead late Saturday after ramming a van into pedestrians on London Bridge and then slashing and stabbing people in nearby Borough Market. During the attack, seven people were killed and dozens more were wounded.
An official at the Bologna chief prosecutor's office said Zaghba was stopped at the city's airport after arriving on a flight from London 2016.
An Italian interior ministry official told The Associated Press that British and Moroccan intelligence and law-enforcement authorities were informed that Zaghba had been flagged as someone "at risk" -- but no other details were released.
The officials spoke on condition of anonymity because they were not allowed to discuss details of the case.
Italian news reports said authorities sequestered Zaghba's cellphone and passport when he was stopped at the airport, but that he successfully got them back after a court determined there wasn't enough evidence to accuse him of any terrorism-related crime.
Italy has expelled more than 40 people in the past two years who were suspected of extremist activities but for whom there was insufficient evidence to bring formal charges. Zaghba's Italian citizenship prevented such an expulsion, Italian daily Repubblica said.
Zaghba was reportedly working in a London restaurant and had not been seen in Italy since 2016.
A British government official who spoke on condition of anonymity because he was not authorized to speak about the investigation confirmed the details of the Italian report, and said the man had not been considered a "person of interest," meaning they had no reason to think he was violent or planning an attack.
Police carried out a new search in a neighbourhood in east London near the home of two of the London Bridge attackers. The search in Ilford, just north of Barking, is seeking to determine whether the group had accomplices.
Police on Tuesday also arrested a 27-year-old man in Barking on suspicion of violating the Terrorism Act and a residence there was being searched.
London police have said 12 other people from the Barking neighbourhood held since the attack have been freed.
The attack, the third in Britain in three months involving suspects who had been on the radar of British authorities, has raised questions over the government's ability to protect Britain following cuts to police numbers in recent years. All three attacks have been claimed by the Islamic State group.
Security has become a key issue in the run-up to Thursday's general election. In particular, there are questions over whether investigators had the resources to look into complaints such as those levelled by Butt's neighbours about his attempts to radicalize children and whether crucial opportunities were missed.
Butt had appeared in a documentary, "The Jihadis Next Door," and was known to investigators, but police said he was not believed to be plotting an attack. Redouane had not aroused any suspicions.
The Islamic gym where Butt worked out said Tuesday they had seen nothing of concern during his time there. In a letter posted outside Tuesday, the Ummah Fitness Centre said staff would "help the police in any way we can."
Neighbours described Butt as an avid weightlifter. Transport for London confirmed he worked for London Underground in customer services before leaving last October.
London Mayor Sadiq Khan said questions would need to be asked about what the police knew about Butt. He has said cuts in the number of police officers have had an impact on the ability to prevent attacks.
Prime Minister Theresa May, who called the snap election in hopes of strengthening her mandate for discussions over Britain's exit from the European Union, has come under fire for the cuts to police numbers over recent years. A string of opinion polls over the past couple of weeks have pointed to a narrowing in the gap between her Conservative Party and the main opposition Labour Party.
The number of police officers in England and Wales fell by almost 20,000 between 2010 and 2016 -- years when May, as home secretary, was in charge of policing.
The area around Borough Market is not expected to reopen Tuesday. Much of the area around London Bridge remained cordoned off as commuters struggled to work in the driving rain.
A minute's silence was observed in Britain at 11 a.m. local time (1000 GMT) in memory of those killed during the attack.
The country's official terror threat level remains at "severe," one notch down from the highest.
It had been set at "critical" in the days after the Manchester concert bombing on May 22 that killed 22 people -- reflecting a judgment that an attack might be imminent because accomplices with similar bombs might be on the loose.
It was lowered once intelligence agencies were comfortable this wasn't the case. Authorities have said the London attack was apparently unconnected to the Manchester bombing.

A British soccer club has applauded the bravery of one of its fans who fought back against attackers in the London Bridge attack.
Millwall Football Club commended Roy Larner, 47, for "his immense bravery in incredibly terrifying circumstances." Larner told the Sun newspaper that he was knifed eight times after attackers targeted a pub where he was out for a night with friends, shouting "This is for Allah!"
He says the attackers were chanting "Islam! Islam!" and that he responded with an obscenity, adding "I'm Millwall."
The club, which has a reputation for violent supporters, says it "stands together with all other football clubs and organizations in offering its absolute support to those in need following the tragic events of last Saturday night."

An Italian prosecutor says one of the London Bridge attackers told authorities at Bologna's airport he "wanted to be a terrorist," but then quickly corrected himself.
Bologna prosecutor Giuseppe Amato said Tuesday and there wasn't enough evidence to arrest or charge Youssef Zaghba when authorities stopped him at the city's Marconi airport on March 15, 2016.
But Amato tells Italy's Radio 24 that Zaghba was flagged to British authorities as a "possible suspect."
Italian newspaper Corriere della Sera reported Tuesday that Zaghba was stopped while trying to take a flight to Turkey on his way to Syria.
Amato says any time Zaghba was in Italy after that, he was always tracked by Italian intelligence officers.
He says: "We did everything we could have done, but there weren't elements of proof that he was a terrorist. He was someone who was suspicious because of his way of behaving."

Family members of a 21-year-old Australian nanny who is missing in London after the London Bridge attacks are pleading for information and raising money to fly her parents to Britain.
Sara Zelenak's mother Julie Wallace told Brisbane radio station 97.3FM that the family had planned to meet Sara in Europe soon.
"We were counting down the days to see her," Wallace said. "The last time I spoke to her was our time Friday afternoon at 4:42 and she said, 'Oh mum! It's only 28 days until you and I and dad can have baguettes and cheese and croissants in Paris."
A woman named Tara who identified herself as Sara Zelenak's aunt said the family is "bracing for the worst." Speaking to media Tuesday outside the family's home in Ormiston in eastern Australia, the aunt called Zelenak a "special, kindred spirit."
London police said Australian woman Kirsty Boden was among the seven killed, and the Australian government confirmed that two Australians are among the injured. Australia's prime minister says officials are working to try to find out what happened to Zelenak.

Surveillance video from a bar in Borough Market obtained by local Spanish newspaper Diario de Pontevedra shows the moment when one of the assailants in Saturday's attack is blocked from accessing a packed bar moments before he was shot by the police.
The camera captured how staff at the Arthur Hooper's bar sheltered customers and other passers-by as the attack unfolded, the newspaper said. As various people try to close off the entrance, manager Sergio Farina can be seen wrestling the door against one of the assailants who is trying to charge against it.
"The police opened fired when one person was stabbed," Farina told the newspaper, adding that the assailant was shot by the police a few metres away from the bar's entrance.
The manager's brother, Rafael, a reporter with Diario de Pontevedra, told the AP that 28 people were sheltered that night in the bar. He said his brother, who has lived in London for 16 years, was more shocked about the events than proud of his action. "My brother doesn't want to be a hero, he just did what anybody would do," said Rafael Farina.

The Pakistani cousin of one of the London Bridge killers said the attack has shattered his family.
Bilal Dar told The Associated Press in the Pakistani city of Jhelum that his cousin, Khurum Butt, lived in the city until he was about 7 years old.
Dar said the last time he spoke to Butt it wasn't obvious that he had turned to radical Islamist beliefs.
"Our family is hurt by what he did," Dar said. "This has destroyed our family's pride."
Dar, 18, said that Pakistani intelligence agents were interviewing relatives.

The mayor of London says he couldn't care less about the accusatory tweets being issued by the president of the United States.
Sadiq Khan told The Associated Press on Tuesday that he "really couldn't be bothered about what Donald Trump tweets."
Trump has repeatedly singled out the mayor of London for criticism following the van-and-knife attack on Saturday night that left seven people dead and scores more injured.
Khan in turn has asked the government to reconsider its decision to invite Trump for a state visit, a move the mayor described as "inappropriate."
Khan spoke to the AP outside the headquarters of London's Ambulance Service following a minute of silence held in honour of the victims of the attack.

The Italian daily Corriere della Sera reported Tuesday that Youssef Zaghba, the third named London Bridge attacker, had been stopped in Italy while trying to go to Syria in 2016.
Zaghba, who was said to be born in Morocco to a Moroccan father and an Italian mother, was stopped at Bologna's Marconi airport on March 15, 2016, while he tried to take a flight to Turkey. He was allegedly on his way to Syria and was carrying only a backpack.
The report said that Italy had put him on a watch list and flagged his presence to Moroccan and British authorities. The parents lived for a time in Morocco and when they separated the mother returned to Italy and re-established herself in Bologna.
Zaghba was reportedly working in a London restaurant and had not been seen in Italy since 2016.
A British government official who spoke on condition of anonymity because he was not authorized to speak about the attack investigation confirmed the details of the Italian report, and said that the man had not been considered a "person of interest," meaning they had no reason to think he was violent or planning an attack.

Australian media reported that Boden was 28 and from Loxton in southern Australia.
Boden was among seven people killed in the Saturday night attacks. Another Australian woman, Sara Zelenak, has been reported missing since the attack.
