MADISON HEIGHTS, Mich. -- A Michigan state police trooper was attacked outside a 7-Eleven store in Madison Heights on Wednesday night.

The trooper stopped at the store on 11 Mile Road and Hampden for a cup of coffee when he heard footsteps behind him upon returning to his squad car, according to a MSP news release.

Before the trooper could turn around, a man jumped on his back and wrapped his arms around the trooper's neck and his legs around the trooper's waist, police said.

Police said the attacker started choking the trooper while yelling that he was from the militia and that the trooper was going to take him up north.

The struggle sent the two men crashing into the side of the patrol car, causing damage to the door, according to the release.

The trooper attempted to break the man's chokehold by throwing his cup of hot coffee on him, but the man would not let go, police said.

The two men were separated after falling to the ground. Police said that's when the man attempted to grab the trooper's gun from his holster, but was unsuccessful. The trooper pinned the man to the ground and radioed for backup while witnesses called 911, according to the release.

Officers from the Royal Oak and Madison Heights police departments responded to the scene and assisted the trooper with the arrest.

While lying on the ground, the attacker told the trooper that he was going to beat the charges, police said.

The trooper suffered abrasions to his knees and left elbow and complained of pain to his left shoulder. The attacker suffered an abrasion to the left side of his face, according to police.

The attacker, from Warren, was described as white, 5 feet 9 inches tall and 145 pounds. His name was being withheld pending an arraignment in 43rd District Court in Madison Heights on Thursday.

He faces possible charges of attempting to disarm a police officer, malicious destruction of police property and resisting and obstruction of a police officer.
