The Bronx prosecutor busted for drunk driving on the Major Deegan bragged to cops that a top boss in her office took care of her previous DWI — and would make this one disappear, too, The Post has learned.

“Call Nestor; he’ll take care of this. He took care of it the last time,” a stumbling, slurring Jennifer Troiano told officers during her arrest last August, a police source said yesterday.

She was referring to Nestor Ferreiro Jr., chief of narcotics in the Bronx DA’s Office, the source said.

Internal Affairs cops are investigating the alleged free pass, and last week hauled at least two of the arresting officers in the August bust in for questioning.

“They were asked specifically if she said anything about the previous incident in which she allegedly got off, and why they didn’t report that she tried to get out of the arrest that night,” a police source said. “They’re trying to figure out if somebody gave her a break.”

A spokesman for Bronx DA Robert Johnson said Ferreiro claims he didn’t do anything to bail out Troiano, 34, in the August bust, or help her avoid a potential felony DWI in December 2009.

“He has not advocated to the police on her behalf on either her August 2010 arrest or any other matter,” spokesman Steven Reed said.

Troiano, a six-year veteran, was picked up on suspicion of drunken driving in 2009 after leaving a holiday party for narcotics detectives. Ferreiro threw a party that year for his bureau at the former Jet Set Café — a Bronx dance club where DJ’s spin reggaeton and salsa.

Troiano refused a Breathalyzer test and was brought to the 44th Precinct, where word got around about where she worked, the source said. Somebody was called, and the charge went away, he said.

When an allegedly drunk Troiano called Ferreiro after the August crash, he told her to tell her boss about the bust, not him, Reed said.

Ferreiro has worked for the Bronx DA for 29 years, and earned $175,000 in 2009, records show. His wife, Cari Ferreiro, also works for the DA as director of litigation training in Johnson’s office, earning about $143,000 in 2009.

Troiano has kept her job, although she has been transferred to the appeals division, and is no longer trying cases.

She has declined comment. Her lawyer, Howard Weiswasser, denied there was any incident in 2009, and predicted she’d be cleared in the 2010 case. Her next court date is June 23.

The revelation came as the DA and IAB are investigating a department-wide ticket-fixing scandal. As many as 40 or more cops could face criminal charges for fixing tickets for friends and family, sources said, and 500 could face disciplinary action.
