SHAFER, Minn. — Three Chisago County sheriff's deputies shot at an assault suspect after he rammed an occupied squad car while fleeing from his home in Shafer Monday, officials said.

The 47-year-old man received only minor injuries caused by crashing his vehicle into the sheriff's squad car, according to authorities.

The man was accused of earlier physically assaulting a convenience store clerk as well as a person who called 911 at the store. Officials say he fired a handgun and used the gun to smash a vehicle's windshield.

The suspect fled before deputies arrived, but they tracked him to his house where they found him leaving.

The man accelerated his vehicle and slammed into the parked squad car, according to sheriff's officials. There are no reports of injuries to deputies.

The Minnesota Bureau of Criminal Apprehension is investigating.
