A man who last year said he had been sodomised by New York police with a truncheon is seeking $US220 million ($A280.58 million) in damages, his lawyer said on Friday.
Tattoo parlor employee Michael Mineo says police held him down on a subway station platform on October 15 and raped him with the baton, tearing his rectum.
His attorney, Kevin Mosley, told AFP he was filing a complaint against New York city, the police force and four officers "based on civil rights violations. Federal law prohibits the excesses."
"Would we not seek some kind of compensation for our life to be ruined? This kind of conduct cannot be tolerated. It has an impact on society," Mosley said.
An officer was charged in December with aggravated sexual assault in the attack and faces up to 25 years in prison if convicted. Two other officers were charged with an attempted cover-up.
The officers say they are innocent. A trial is expected in September.
