Bronx cops spared a prosecutor from a potential DWI arrest after she was brought into the same precinct as her courtroom — raising questions that officers are willing to quash crimes far more serious than traffic tickets.

Jennifer Troiano was pulled over in December 2009 and identified herself as an assistant district attorney, said a police source.

The Cardozo Law School grad was brought to the 44th Precinct station on East 169th Street, where “word got around who she was,” said the source.

“Somebody was called on her be half, and it went away.”

No arrest number or other pa perwork was generated, the source added, and she was al lowed to leave.

“I don’t want to talk to you,” Troiano, 34, barked as she left a hearing yesterday for a sepa rate 2010 DWI bust that is headed to trial.

Steven Reed, spokesman for the Bronx District Attorney Robert Johnson, said: “At the time of her arrest in the pending case, it was mentioned that she had previously been detained and released. We have not uncovered any specifics with respect to that.

“As for any disciplinary action, we do not discipline employees based solely on an arrest.”

Troiano, who has been with the office for six years, is due back in court on June 23 for the 2010 case.

In that incident, “she was stumbling, falling down unable to get her balance,” arresting Officer Lawrence Harvey wrote when he arrived on the scene after a three-car crash on the Major Deegan Expressway.

“She was on the cellphone walking in lanes of traffic,” he said, according to court records.

Then Troiano allegedly tried to talk her way out of the jam.

“She stated, no foul, no foul, my insurance will cover it,” Harvey wrote in his report. “I didn’t do anything wrong. My car was in the front and I’m not even supposed to be driving.”

She refused to take a Breathalyzer, a source said.

After her bust, Troiano’s direct supervisor, Hannah Freilich, handled the case for about a month, court documents show, including interviewing the arresting officers.

It took several weeks before Freilich finally recused herself.

In another twist on the larger ticket-fixing probe, a lead NYPD Internal Affairs detective on the case was disciplined for using a Police Department computer for his off-duty real-estate business.

The misuse of public property occurred amid his ticket-fixing investigation, and he lost several vacation days as punishment, sources said.

Internal Affairs was also worried that its own members were leaking details of the investigation to cops under scrutiny in The Bronx, so it brought fresh IAB detectives from other boroughs, a source said.

At least 40 Bronx cops face criminal charges, and as many as 400 cops from around the city face internal disciplinary actions for allegedly fixing traffic tickets for friends, family and people with connections.

Prosecutors are investigating if some officers accepted — or solicited — gifts or bribes, sources said.
