A retired NYPD officer who allegedly lied under oath has landed a sweet gig at the Rockland County District Attorney’s office.

The office sought a special state waiver to hire Matthew Wohl for a job as a confidential investigator, which pays $94,000 a year on top of his police pension. The waivers are required for government workers who want to collect both their pensions and an annual salary of more than $35,000 from government agencies.

The former cop, who retired from the NYPD in July 2021, testified in the 2005 trial of a protester arrested during the 2004 Republican National Convention in Manhattan. He said he helped carry the kicking and screaming protester down the steps of the New York Public Library.

But video contradicted Wohl’s account, reportedly showing the protester walking down the stairs on his own and the officer nowhere in sight. This led prosecutors to drop the case and the FBI to investigate. He does not appear Wohl was charged and it’s unclear if he was disciplined.

Wohl landed on a list maintained by the Bronx District Attorney’s office of officers with potential credibility problems.

The Post reported this week that at least 16 police officers arrested between 2017 and 2021 were allowed to keep their jobs although an NYPD administrative trial judge found them guilty of the acts they were accused of.

The DA’s office contended it needed to hire Wohl because two other applicants did not meet the minimum qualifications for the job, according to a state document analyzing the waiver application obtained by The Post. But the document strangely went on to list the minimum qualifications as “N/A.”

State law requires agencies that want waivers to prove they have “undertaken extensive recruitment efforts to fill such vacancy” and that “there are no available non-retired persons qualified to perform the duties of such position.”

Wohl is one of six double dippers in DA Tom Walsh’s office, according to a source.

Among the others with waivers are Peter Walker, a former detective and the public information officer for the Clarkstown Police Department in Rockland. He is now pulling down a $191,000 salary as the DA’s chief criminal investigator — a significant jump in rank — plus $144,000 pension, records show.

“It’s absolutely astonishing,” said a source familiar with the DA’s office.

Neither Walsh nor Walker, listed as a press contact for the office, returned requests for comment. A man who answered a phone number listed for Wohl said he wasn’t the retired officer.
