NEW YORK — A former New York City police commissioner has been accused of backing his SUV into a pregnant woman, then driving away. Police say Howard Safir bumped the woman with his Cadillac Friday afternoon in Manhattan. She was treated for a bruised shoulder, but wasn't seriously hurt. Police detectives decided not to press charges. They say Safir didn't know he'd hit someone. The victim tells a different story. Joanne Valarezo tells The New York Times that both she and a passenger in the SUV yelled at the driver for being careless before he drove away. She says she didn't know who he was until informed by a reporter. Safir was police commissioner from 1996 to 2000. Calls to his homes in New York and Maryland weren't immediately returned. ___ Information from: The New York Times, http://www.nytimes.com
