The family of a Bronx man who died after being cut and Tasered by cops while blocking them from entering his room is now suing the city for $25 million – claiming they violated his civil rights and used excessive force.

Emergency Services Unit cops were called and responded to an “emotionally disturbed person” last July at a Bronx halfway house, where Anthony Paul II naked and locked in his room, according to the Manhattan federal court lawsuit filed Wednesday.

After inserting a camera into his room, cops tried to coax him out and attempted to unlock his door to no avail before using a saw to bust through the door, the suit says.

Paul, who was trying to “guard” the door, was cut on his hands and arms more than 30 times – causing him to “bleed profusely” — and Tasered at least twice once cops broke through, according to documents.

The lawsuit alleges cops used “excessive physical force and unnecessary” Tasers in violation of protocol in order to arrest him.

A bloodied Paul was taken to North Central Bronx Hospital but his family contends the facility was negligent by not giving him sedatives to slow his heart rate.

He later died.

A spokeswoman for the city Medical Examiner’s Office said Paul’s cause of death was “cardiac arrhythmia due to agitated delirium (probable drug intoxication)” and ruled an accident.

“Anthony Paul II’s only issue, one that he could not control, was to be suffered from an emotional disturbance,” says the suit filed by Paul’s father Anthony Andre Paul and uncle Alberty Paul.

“Yet, despite being locked in a room, not presenting a danger to himself or anyone else, members of the NYPD violated Mr. Paul’s constitutional rights and their own policies by sawing their way into his room, cutting and slashing Mr. Paul in the process.”

The family accuses Commissioner Bill Bratton of “[trying] to cover up the NYPD’s offensive conduct” by saying a month later that Paul was high on synthetic marijuana when he died.

“…This individual was so out of it, he literally grabbed hold of this electric saw with both hands and was totally impervious to the pain that was being inflicted upon him, and it took quite a few efforts on the part of our officers to ultimately subdue him,” the lawsuit quotes Bratton as saying.

The family says two different toxicology tests showed Paul did not have synthetic marijuana in his system at the time.

It also claims the NYPD has refused to turn over any video that captured the disturbing incident.

“It is unconscionable that Mr. Paul was allowed to be beaten and tortured for no reason and that the police commissioner attempted to cover up the officers’ barbaric behavior with lies,” the family’s attorney Derek Sells said.

A spokesperson for the NYPD didn’t return a message for comment.

A city Law Department spokesman said it would review the lawsuit.
