Former city Department of Buildings commissioner Eric Ulrich surrendered to the Manhattan District Attorney Wednesday morning with a copy of Bill O’Reilly’s “Killing Jesus” in his hands.

The exact charges against Ulruch are currently unclear, but he is expected to face bribery and mob-related charges.

His arrest is part of a wide-ranging corruption probe from the Manhattan District Attorney’s Office that has also ensnared a top donor to New York City Mayor Eric Adams, sources said.

Ulrich, 38, resigned from the Adams administration in November after it was revealed that he was under investigation and had turned his cellphone over as part of a criminal gambling probe.

The former career politician will face a judge at a 2:15 p.m. hearing, his lawyer Sam Braverman earlier told The Post.

Manhattan District Attorney Alvin Bragg will hold a news conference at 1 p.m. Wednesday in Lower Manhattan.

Sources told The Post on Tuesday that prosecutors were looking into whether Ulrich got into debt playing card games linked to organized crimes, with the alleged matches going back to his time as a Queens city councilman.

Ulrich was not charged at the time and prosecutors continued their investigation, seemingly paying closer attention to possible favors exchanged by the pol – and news breaking over the summer that a grand jury had been hearing evidence against him and that a criminal indictment was imminent.

He is one of several people expected to be arrested Wednesday.

Others include Brooklyn real estate developer Mark Caller, who will is likely to face charges related to his alleged offering of a discounted apartment to Ulrich, as well as Queens pizzeria owners and brothers Joseph and Anthony Livreri.

Caller raised nearly $50,000 toward Adams’ mayoral campaign, according to law enforcement sources.

His lawyer, Benjamin Brafman, said on Tuesday that his client “intends to plead not guilty and we anticipate that he will be fully exonerated.”

The Liveri brothers, who co-own a Queens pizza shop with alleged mafia ties, co-hosted a fundraiser for Adams’ mayoral campaign in August 2021.

Ulrich — who as of January had been selling insurance to make ends meet —  recently wrote a children’s book in which dogs are judges and juries in the court system.
