The NYPD will launch a probe into memos at a Brooklyn stationhouse that appeared to set quotas for traffic summonses, Mayor Bloomberg said.

The move comes after the Daily News reported that at least two notices posted at the 77th Precinct stationhouse spelled out the number of tickets needed in a specific time frame.

That’s illegal under state law – and runs counter to the Police Department’s public no-quotas stance.

The NYPD said an officer posted the memos without authorization. A police source said they were put up inside the roll call room by a highway safety officer.

Bloomberg promised an investigation. “Commissioner Kelly will look at it,” Bloomberg said, calling the postings an aberration.

“We don’t have quotas,” he said, “but we certainly have performance management.”

The NYPD had no comment.

Officer Adrian Schoolcraft, the whistleblower cop from Brooklyn’s 81st Precinct, has accused his supervisors of imposing quotas, and cops in two Bronx precincts have made similar allegations in recent months.

In 2006, an arbitrator ruled that the NYPD violated state labor law by using traffic summons quotas in the 75th Precinct in Brooklyn, punishing cops who didn’t meet them.

The arbitrator cited a directive from the commander at the time, Deputy Chief Michael Marino, that linked performance evaluations to summons and arrest numbers.
