Five people involved in last weekend’s melee with cops at the Marcy Houses housing project in Brooklyn plan to sue the city and the NYPD for a combined $85 million — claiming they were victims of police brutality.

Three men and two women — four of them taken into custody during the clash — claim they were roughed up by cops and suffered injuries including a shattered jaw and a whack to the head with a police baton, their lawyers said Wednesday.

“Not only are they injured … but now they have to face criminal charges when they did nothing wrong,” said civil rights attorney Sandy Rubenstein, who filed a notices of intent to sue with the city Wednesday morning.

“But I really believe we need to hold these police accountable criminally, when they commit criminal acts against individuals who have done nothing wrong.”

Three officers were hurt in the weekend skirmish at the Bedford-Stuyvesant housing project, during which the NYPD said officers were swarmed by a boozed-up crowd, while other locals hurled projectiles from buildings and fired guns into the air.

The unrest began around 11 p.m. Saturday when officers responded to reports of a large and unruly crowd at the housing complex, where tenants were holding an annual “Marcy Day” event, according to cops.

But the crowd turned violent when officers tried to break it up and placed one person under arrest, the NYPD said.

Four people were arrested — including a 17-year-old accused of head-butting a cop — while 11 were summonsed.

Of the individuals who announced plans to sue the city, three of them — Jeffrey Lloyd, Ron Fernandez and Lawrence Lee — were cited for disorderly conduct and released on desk appearance tickets.

A fourth, Unique Silver, was charged with resisting arrest, obstruction, disorderly conduct and drinking in public and released without bail.

The fifth, Ja-Nay Graham, was not charged, but claims she was slammed in the head by an officer’s nightstick while she was filming the clash and needed five staples to close the gash.

“I didn’t do anything,” Graham said Wednesday. “I wasn’t arrested because I was innocent. I was just trying to find out what happened to my nephew and that happened to me.”

“The police were using straight excessive force on everyone. It was a good day, nobody was fighting, nobody was arguing,” she said. “They were just pushing and spraying mace at kids and pushing kids. It was all uncalled for.”

Two of the five plan to sue for $5 million each, and the other three for $25 million each.

The city declined to comment, saying they had not been served with Rubenstein’s notice of intent. The Brooklyn District Attorney’s Office also declined to comment.

A spokesperson for the NYPD said they “will review the lawsuit once we are served and the matter is under internal review.”
