A Baltimore police officer was bitten while responding to a call about a marauding pit bull in the Winston-Govans neighborhood. Before noon Saturday, officers responded to the 500 block of Winston Ave. after a report by an unidentified man, who worked for a home improvement company, saying he and a boy had been bitten by a pit bull. When the officers arrived, the pit bull was running loose and bit one officer in the thigh, while another officer fired at the dog and missed, according to police spokesman Donny Moses. Animal Control was notified and captured the dog. The officer was treated at Mercy Medical Center. The man who was bitten in the hand refused medical attention. The boy, who was bitten in the arm and the hand, was transported to Johns Hopkins Hospital, where he was reported to be in good condition, Moses said.
