Plea to keep Finest brass out of prison

A FORMER high-ranking cop who pleaded guilty to misusing police resources to help a donor to Mayor de Blasio doesn’t deserve jail time because inmates will target him behind bars, his attorney argues in papers filed Tuesday.

Former Deputy Chief Michael Harrington, 52, (photo) admitted in March to doing an array of onduty favors for Jeremy Reichberg, including ordering a helicopter flyover of a party in 2015 the Brooklyn businessman held on a boat in the East River.

He also admitted to arranging an NYPD harbor unit ride-along for Reichberg and some of his guests at a barbecue that year.

In new papers filed in Manhattan Federal Court, Harrington’s attorney Andrew Weinstein writes that the disgraced cop deserves a sentence of probation. Federal guidelines recommend Harrington be sentenced to up to six months in jail.

Harrington pleaded guilty in connection with a sprawling giftsfor-favors probe that rocked the upper ranks of the NYPD. He will be sentenced on June 11.
