Columbia University Professor Joann Baney Charged with Assaulting Boyfriend

In a strange turn of events, a New York City college professor who trains police and firefighters how to diffuse heated situations has been charged with misdemeanor assault.

Joann Baney, an adjunct associate professor at Columbia University’s School of International and Public Affairs, is accused of assaulting her longtime boyfriend, Walter Frey, 46, while he slept inside her Upper West Side apartment about 10:45 p.m. on Saturday, the New York Daily News reports.

“I hit him because he cheated on me,” Baney told a cop who responded to the assault on Valentine’s Day, according to the newspaper. Frey, a retired NYPD sergeant, sustained cuts to his left ear and the right side of his neck.

Baney, 54, is reportedly a defender of women’s rights and an outspoken critic of domestic violence. She is on the faculty of the NYPD’s Police Management Institute and author of the book Guide to Interpersonal Communication.

Court documents obtained by PEOPLE show that she was charged with multiple counts including assault, intent to cause physical injury, attempted assault with intent to cause physical injury, and harassment.
