MONTREAL -- The wife of alleged fraudster Arthur Porter has turned herself into police and is facing a new charge.

Pamela Porter arrived at Quebec provincial police headquarters in Montreal this morning.

She faces a new charge of money laundering as Quebec's anti-corruption unit alleges some of the money used to secure her bail in 2013 came from proceeds linked to alleged fraud of $22.5 million.

Porter is among several people who are charged in the awarding of a $1.3-billion contract for the McGill Superhospital in 2010, a group that includes her husband.

Pamela Porter already faces one charge of conspiracy and another related to the alleged money laundering.

She is expected to appear before a judge on the new charge later today.

Porter told CBC News on Wednesday she hopes to force the Crown to grant her a trial sooner and that she won't seek bail again.

Currently, a preliminary hearing in her case is only expected in March 2015.

Arthur Porter is the former head the McGill University Health Centre and was once appointed by Prime Minister Stephen Harper to head the Security Intelligence Review Committee, a CSIS watchdog group.

He is still in a jail in Panama where he is fighting his extradition to Canada.
