At least half a dozen NYPD officials are out the door as a new administration settles in — including the department’s internal prosecutor who was canned after she recommended disciplinary action for the force’s highest-ranking uniformed cop, The Post has learned.

Department Advocate Amy Litwin was fired on Aug. 7, three days after newly-named Police Commissioner Edward Caban announced the departures of “several” senior members of the NYPD’s executive team.

While Caban did not name the departing officials in the press release, they include Chief of Detectives James Essig and Transportation Chief Kim Royster, both NYPD veterans and holdovers from Mayor Bill de Blasio’s administration, police sources said.

Shake-ups are common under new leadership, but the timing of Litwin’s termination raised eyebrows in the department, the sources said.

Rarely in the public eye, Litwin believes she made an enemy of influential Chief of Department Jeffrey Maddrey after she sided with the police’s civilian watchdog and recommended that former Commissioner Keechant Sewell discipline him over a voided gun arrest case from 2021, according to a source close to her.

The department advocate is tasked with re-investigating all sustained charges from the Civilian Complaint Review Board and signing off on recommendations for discipline before any reprimands are formally issued to officers.

Maddrey’s command discipline, which he is challenging internally, caused a rift between Sewell and City Hall, pushing the top cop to her breaking point before she ultimately resigned abruptly, The Post previously reported.

Litwin, whose last day was Aug. 18, was named to the post in June 2020 by then-Commissioner Dermot Shea after working at the Bronx District Attorney’s Office.

She was kept on by Sewell when the latter was named police commissioner at the start of Mayor Eric Adams’ tenure in Jan. 2022.

The two shared the connection of being seen as outsiders in the department, with the department advocate running afoul of the police unions and the CCRB, according to the sources.

The NYPD did not comment on the reason for her termination, or the departures of the other more-senior members of the department, who also include Assistant Commissioner Gene Whyte and Christopher McCormack the assistant chief of detectives.

“As is customary with any new administration, changes will occur within the upper echelon,” newly appointed Deputy Commissioner of Communications Tarik Sheppard said in a statement.

“Those changes are being made with a great deal of care and consideration. Commissioner Caban is building a strong team to help lead the NYPD into the future and that work remains ongoing.”

Litwin did not return calls for comment.
