Fresh off the convictions of Sheldon Silver and Dean Skelos, the head of public corruption for Manhattan US Attorney Preet Bharara is leaving public service for richer pastures, The Post has learned.

Arlo Devlin-Brown, who was anointed chief of Bharara’s public corruption unit in 2014, has accepted a job at international law firm Covington & Burling, where former U.S. Attorney General Eric Holder is a partner.

Andrew Goldstein, one of prosecutors who helped take down former NY Assemblyman Silver, is expected to replace him, sources told The Post.

The changing of the guard comes as the FBI and Bharara’s prosecutors probe people close to governor Andrew Cuomo, including lobbyist Todd Howe and former aid Joe Percoco, over improper lobbying and undisclosed conflicts of interest.

Bharara’s office is also conducting a probe that has ensnared Mayor Bill de Blasio, including over a deal that allowed a Lower East Side nursing home to be flipped to a luxury condo developer, netting the seller a $72 million profit.

The feds have also been hot on the trail of a gifts-for-favors scandal that is expected to result in the arrests of several NYPD officers.

Devlin-Brown joined the U.S. Attorney’s Office in 2005. Prior to becoming the chief of the public corruption unit, he was part of the team known for prosecuting former SAC Capital portfolio manager Mathew Martoma, who was convicted of insider trading charges that helped force billionaire Steve Cohen to stop managing outside money and rename his firm Point72 Asset Management.

“It’s been a great honor to serve in the U.S. Attorney’s Office for more than a decade, where I have had the privilege of challenging cases involving fraud and corruption in the worlds of finance and politics alike,” Devlin-Brown said in a written statement.

He will join Covington’s white collar defense and investigations practice as a partner and be based in the New York.
