A good Samaritan pulled a woman from a car that had rolled over and caught fire early Wednesday morning in North Attleborough, a fire official said. The woman, who has not been identified, was transported to Rhode Island Hospital in Providence. “The woman sustained serious injuries, but we don’t know the specific extent,” said North Attleborough Fire Lieutenant Chris Coleman. The rescuer, who was not involved in the accident, was not injured. Firefighters responded at 4:45 a.m. to the accident on Interstate 95 southbound.
