Two men arrested over the weekend on charges of aggravated assault with a knife after an incident in the Ammon Walgreen's parking lot.
The Bonneville County Sheriff's Office said Justin Crosby, 22, and Jordan Crosby, 21, both of Idaho Falls, drove at a 36-year-old man in the parking lot at a high rate of speed Saturday around 10 p.m. and then threatened him with a knife.
Deputies later arrested them at the Grand Teton Mall. A third man in the vehicle was not arrested.
The sheriff's office said the men did not know the victim.
