A New York City police officer accused of forcibly shoving a police baton into a Brooklyn (New York City)" id="PLGEO100100802010000">Brooklyn man's rectum as he was being searched on a subway platform will be indicted on charges of aggravated assault on Tuesday, according to the accuser's attorney.

Stephen C. Jackson, attorney for Michael Mineo, 24, said in a telephone interview on Sunday that a Brooklyn grand jury has voted to indict Police Officer Richard Kern, 25, on charges of aggravated assault.

At least two of the three other officers involved in the Oct. 15 incident -- Noel Jugraj, 30, Andrew Morales, 26, and Alex Cruz, 26 -- will be indicted on lesser charges, Jackson said.

The indictment is expected to be unsealed on Tuesday. A spokesperson for the Brooklyn District Attorney's office declined to comment.

Mineo accused the four police officers of pinning him down and shoving what was initially believed to be a radio antenna into his rectum as he was being searched by police while inside the Prospect Park subway station.

Officer Kevin Maloney, a transit cop, reportedly testified during the grand jury proceedings that he witnessed Kern shove a baton into Mineo's exposed buttocks. Maloney is not facing any charges.

Mineo called in to the Al Sharpton" id="PERLL000236">Rev. Al Sharpton's radio address at the Action Network News headquarters in Harlem on Sunday. "I am pleased about the news and I thank the officer for coming forward," he said, "as well as the community and Rev. Sharpton for believing me when many questioned whether I was telling the truth."
