Former state Comptroller Alan Hevesi turned himself into law enforcement authorities in Manhattan early this morning and is due to be arraigned at 9:30 a.m., a source familiar with the proceedings confirmed.

After his arraignment, Hevesi is scheduled to be in the courtroom of state Supreme Court Justice Lewis Bart Stone, who has handled all the criminal proceedings to date in AG Andrew Cuomo’s pay-to-play pension fund probe. When Hevesi issues his plea he is expected to also detail his involvement in the scheme before the court.

Last week, the Times reported Hevesi was in negotiations with Cuomo’s office for a plea deal that would require him to plead guilty to a second felony corruption charge and do time in prison.

At the time, Cuomo’s office said the deal was not yet soup, but also did not deny that talks with the former comptroller were in the works.

There has been speculation that Hevesi is willing to deal with Cuomo in hopes of protecting his sons – Assemblyman Andrew Hevesi and former Sen. Dan Hevesi – who have also be touched by the AG’s probe.

As you’ll recall, Hevesi has already pleaded guilty to a felony corruption charges in connection with the so-called Chauffeurgate scandal in which he misused state employees as aides to his ailing wife.

That plea came after the former comptroller won re-election in 2006, defeating his GOP opponent, former Saratoga County Treasurer Chris Callaghan, in spite of the ethical cloud that hung over him at the time and the dis-endorsement of then-AG/gubernatorial candidate, Eliot Spitzer.

UPDATE:

AP is now reporting that Hevesi is expected to plead guilty to a felony corruption charge. It goes on to say Hevesi is accused of accepting rewards and gifts for official misconduct.
