State troopers say a man is facing charges after a road rage incident involving a gun and a knife on Interstate 81 Monday afternoon.

According to the Tennessee Highway Patrol, the victim called police and reported a vehicle driving recklessly and weaving in and out of traffic on I-81 north near mile marker 33 in Greene County.

THP says the incident came to a climax when Matthew Pilkington, 35 of Elizabethton, pulled out a gun and pointed it at the victim.

Troopers caught up to Pilkington’s 2008 Ford Focus on Interstate 26 at mile marker 13 and pulled him over.

THP says they found a black airsoft pistol behind the driver’s seat and also recovered a knife, which Pilkington admitted to waiving at the victim.

Pilkington was arrested and taken to the Greene County jail. The highway patrol has charged him with aggravated assault and open container.
