PROVIDENCE, R.I. — A Providence police detective who's charged with assaulting his girlfriend has turned around and brought criminal charges against the woman.

The Providence Journal reports that 45-year-old John Black filed three simple assault charges against the 26-year-old woman. Rhode Island residents can file misdemeanor criminal charges under a little-known and rarely used law upheld by the state Supreme Court in 2001.

The woman told police they had been arguing and Black assaulted her when she refused to let him into her apartment. She says he took her cellphone when she tried to call 911.

Black says the woman threatened to tell his wife and became violent when he said he didn't want to continue their relationship.

Black pleaded not guilty to assault. He's free on bail and has been placed on administrative duty.
