Misconduct complaints against New York City police officers have increased under Mayor Eric Adams’s administration and last year were at their highest since 2014, according to a report that measures the performance of city agencies.

In the 2025 fiscal year, which ended June 30, there were more than 5,570 reports to the Civilian Complaint Review Board, the Police Department’s oversight agency, a roughly 60 percent increase from 2022, according to the Mayor’s Management Report, which was the subject of a testy City Council committee hearing with police officials on Monday. The number touched a decade high in 2024.

Mr. Adams, a former police captain sworn in as mayor in January 2022, vowed to crack down on crime when the city, like many others, was experiencing a surge in homicides, shootings and other major crimes in the post-pandemic era. He brought back a specialized police unit that had been disbanded under his predecessor, Bill de Blasio, and was unapologetic about tactics that he said helped sweep guns off the streets.

The overall number of felonies, including shootings and homicides, fell during Mr. Adams’s time in office, according to the report, though other crimes, such as rapes and assaults, increased.

“We have made good on our commitment to make our city safer,” Mr. Adams wrote in a letter introducing the report, which is mandated by the city’s charter and was released last Wednesday.

But Lincoln Restler, a City Council member who represents parts of Brooklyn, said Monday that he was “very concerned” by the spike in complaints, which the report showed rose in categories including the use of force, abuse of authority and the use of offensive language.
