A Halifax man who stole an Apple MacBook Pro had several high-powered weapons in his pickup truck, including a Bushmaster rifle, when police arrested him Friday in East Boston, authorities said.

Boston police said today in a statement that days before his arrest, Peter Hilliard, 48, allegedly broke into a house in an unspecified community outside the city and stole the MacBook, which he then dropped off for servicing at a store on Meridian Street in East Boston.
