NYPD Chief of Department Jeff Maddrey wanted criminal charges brought against three teens who hit a retired cop’s security camera with a basketball — all while voiding the ex-officer’s arrest after he allegedly menaced the youths with a gun, the police’s civilian watchdog found.

The Civilian Complaint Review Board’s closing report on the controversial November 2021 incident, obtained by The Post, states that Maddrey personally ordered a Brooklyn precinct sergeant to void the arrest of retired NYPD Officer Krythoff Forrester.

Maddrey then insisted the boys — ages 12, 13 and 14 — should have been booked instead, the report says.

The report led the CCRB earlier this month to substantiate one count of abuse of authority against Maddrey over the incident, for which he could face a maximum punishment of 10 docked vacation days.

Maddrey — who was the head of community affairs at the time — had gotten word from inside the department that Forrester was arrested late in the evening of Nov. 25, 2021 for menacing after he allegedly pulled a gun and chased the group of teens, who said they accidentally damaged a camera outside the ex-cop’s family real estate office in Brownsville.

Maddrey — who knew Forrester from his time as the 73 precinct commander — went to the stationhouse at around 11 p.m. that night and ordered a voiding of the retired officer’s arrest, which had been investigated and approved by a sergeant, according to the CCRB report. He then allegedly told the sergeant that the teens should have been booked for damaging the camera.

“Chief Maddrey expressed that a police report or a juvenile report should have been made, and that the children should have been brought back to the stationhouse, given the video evidence showing them damaging the surveillance camera,” reads the report.

The comments stand in contrast to recent public comments from Maddrey, who just months ago touted his department’s ability to reduce “negative encounters” with the city’s young people.

In one of his first public appearances in his current post as the NYPD’s highest-ranking uniformed officer, Maddrey championed the work cops have done to avoid bringing kids into the criminal justice system.

“We will continue to build on the neighborhood policing philosophy and through our youth coordination officers increase our reach into the lives of young people to prevent negative encounters with the criminal justice system,” he said on Jan. 5 at NYPD headquarters during a press conference highlighting end of year crime stats.

Maddrey, who was promoted from chief of patrol in November, is facing heat over the CCRB investigation and findings.

The Brooklyn District Attorney’s Office reviewed the incident and deemed his actions did not warrant criminal charges. But the New York Attorney General’s Office opened its own probe into the case after news of the CCRB charge broke, state sources said.

According to the CCRB report, Maddrey did not explain to the watchdog how he determined that Forrester should not face charges.

He told the sergeant that there was no evidence a gun had been brandished aside from the account of the kids, but claimed their story wasn’t credible because he believed they had lied about accidentally breaking the camera, the report states.

Maddrey also told the sergeant he would use the incident “as a learning experience” and that “the worst thing that can be done is to place an innocent person in jail,” according to the report.

The sergeant, however, believed the detail in which the kids described the gun was more than enough to arrest and charge Forrester.

“There’s too many coincidences that …That’s a very distinctive gun …They told me they pulled it from the side of the waist where he has his holster …It’s hard to say someone’s got a gun, and describe the gun, and then that guy has a gun, and it matches,” the sergeant said, according to the report.

Forrester admitted to carrying his gun on his hip and telling the kids he was armed, but he denied pulling the firearm.

“I said don’t come back. You come back I’m going to shoot you. But I didn’t take it out,” Forrester told cops, according to the CCRB report.

But Maddrey allegedly instructed the sergeant to “merely” write in the report on the incident that Forrester had chased the teens, leaving out mention of a gun, according to the CCRB.

“The absence in the arrest report of any mention of a firearm… also illustrates an effort to downplay the accusations against [redacted] in the police record, while still pointing to the offense by the children of breaking the camera,” the report concludes.

An attorney for the boys has called on Maddrey to resign.

Mayor Eric Adams defended the police official last week saying he was “proud” that Maddrey was his Chief of Department.
