A case of alleged road rage has landed a teenager and his mother behind bars.

Police say 18-year-old Eric Mutrie was arrested after he severely beat up a 70-year-old man. They also say Mutrie had some help. The teen's 53-year-old mother, Rhonda Mutrie, was also arrested.

Police say it happened last Wednesday.

Witnesses say the victim was hit so hard that his teeth were knocked out and he had to get about 40 stitches in his upper lip.

Both the teenager and his mother have been booked on charges of second-degree battery.
