An RCMP officer in Queens County had to fire off a warning shot to scare away an aggressive pit bull while making an arrest in Liverpool this weekend. Police were executing a search warrant on Sunday at a home in Mersey Point when they were greeted at the door by the large dog. According to police, the pet was not harmed and the officer only fired his revolver to scare away the dog. Meanwhile, police arrested a 24 year-old man in relation to an alleged break and enter in the area. The man has been charged with possession of stolen property, break and enter and two counts of breach of probation. The accused was scheduled to appear in Liverpool Provincial Court today.
