Manchester - Three men were arrested last night over the killing of five-year-old Dillon Hull, shot in the street in a drugs-related attack a week ago. Police from a firearms unit swooped on a house in the Deane area of Bolton, close to Dillon's family home, and arrested the men. They were being held at police stations in Bolton and being interviewed by detectives. A massive hunt had been going on since the youngster was shot while walking to a shop with his stepfather, Mr John Bates (28), from the family home in Jauncey Street last Wednesday. Police said they believe the shooting, in which Mr Bates was wounded in the stomach, may have been drugs- related.
