RUMFORD — A woman and her teenage daughters were attacked Wednesday by a neighbor’s pit bull and treated at Rumford Hospital, police said. Police got a call at 10:25 a.m. from an Erchles Street resident who said a pit bull was attacking a neighbor and not letting go of her leg, Chief Stacy Carter said in a news release. He said a preliminary investigation revealed the dog had gotten out of its house and was running loose. It went to a neighbor’s home, where it bit a 17-year-old girl, then bit her 18-year-old sister.
