BROOKLYN - Three NYPD officers accused in a subway station baton sex attack went on trial Thursday in Brooklyn.

Officer Richard Kern is charged with aggravated sexual abuse and assault. He is on trial with officers Alex Cruz and Andrew Morales, who are accused of covering up the attack. They are charged with hindering prosecution and official misconduct.

Prosecutors say Michael Mineo, the alleged victim, was sodomized inside the Prospect Park subway station, where he bolted after being seen smoking marijuana by the officers.

AP wire services were used in this report.
