A couple of Indiana brothers are in jail after they allegedly attacked a Michigan State Police trooper along the side of US-31 Monday morning in Berrien County. Michigan State Police say the trooper tried to pull over an unlicensed motorcyclist near Matthew Road in Berrien Township when the motorcyclist took off at a high speed. That resulted in a three mile chase which ended when the 21-year-old lost control of the bike. He then attacked the trooper. During that struggle, the motorcyclist’s brother pulled over and also started fighting with the trooper. Two passersby then stopped and steppedin , making it possible for the trooper to arrest the brothers. Police say the motorcycle was stolen out of Van Buren County, and the brothers may have been involved in several recent break-ins. Their names haven’t been released.
