A special investigative grand jury will examine evidence in the Brooklyn case of a 24-year-old male claiming to have been sodomized by a group of five police officers with a police radio antenna some two weeks ago.

Michael Mineo, 24, claims to have been subjected to police brutality on October 15, inside a Brooklyn subway station, when five police officers, one of them a transit bureau officer, approached him, attacked him for no reason and sexually assaulted him with what he believes to have been a radio antenna.

He checked into Brookdale University Hospital and Medical Center, where he spent four days and received treatment for severe abdominal pain and rectal injuries, his lawyer, Kevin Mosley, said. Mineo returned last week to hospital with a stomach abscess, related to the attack, the lawyer said. His medical records have not been made public yet.

Police officials said Mineo, who works at a tattoo parlor in Brooklyn, was arrested on the afternoon of Oct. 15 because he was smoking marijuana. When officers approached him, he tried to escape by running into the subway. They followed him and he resisted arrest. After issuing him a summons he was released.

Authorities also say witnesses at the scene do not support Mineo’s claims of being assaulted – the witnesses said they did not see either of the police officers holing a baton or radio. Two witnesses did say that they heard Mineo scream he was being sodomized and tasered but the police officers were doing no such thing. Mineo was issued a summons for disorderly conduct, a police spokesperson said.

The locker of one of the five officers accused was searched one day after the alleged Oct. 15 attack on Mineo and a baton and radio antenna were seized and processed for evidence. DNA tests did not reveal any organic matter. Results from more sophisticated DNA tests are pending.

The four police officers remain on active duty. They still have their guns and shields. They were given desk jobs Monday to shield them from the media, reports the New York Daily News quoting officials. The NYPD transit cop arrived after the alleged assault and is considered a witness. All four officers are assigned to the 71st Precinct.

Brooklyn District Attorney Joe Hynes issued a statement Monday, announcing that a special investigative grand jury is to be convened at his order, based on his own investigation so far and review of medical evidence.

The police Internal Affairs Bureau is also investigating.
