The government witness who helped convict former top Gov. Cuomo aide Joe Percoco of bribery has agreed to remain behind bars until the feds are done using him as a witness in their sprawling Albany corruption probe, his lawyer said Tuesday.

Todd Howe, who was tossed in the slammer for violating his parole in the middle of Percoco’s high-profile bribery trial, has agreed to remain locked up until the feds need him next, the lawyer, Richard Morvillo, said in Manhattan federal court.

Prosecutor Robert Boone said that could be as soon as June, when Howe may be called to testify in the trial of Buffalo developer Louis Ciminelli over an alleged bid-rigging scheme.

As a result, the judge set a preliminary date of Aug. 1 for Howe’s sentencing, although it could be pushed back further if the feds decide to use him in the retrial of a Percoco co-defendant whose case was dismissed due to a hung jury.

Howe, who appeared at Tuesday’s hearing in ankle chains and handcuffs, faces as much as 10 years in prison when he is sentenced for his role in the corruption case. He likely would have received much less, until his parole violation, which now leaves his fate unclear.

He was tossed into Manhattan’s Metropolitan Correctional Center in February after he admitted he tried to scam his way out of a $600 stay at the Waldorf Astoria hotel while cooperating with the feds.

Despite the arrest, he helped convicted Percoco by testifying that he served as the middleman in a “pay-to-play” scheme that funneled $300,000-plus in bribes to Percoco when he was a Cuomo aide.
