Police have arrested a naked carjacking suspect who allegedly caused two separate car collisions that injured seven people in Scottsdale.
Authorities say John Brigham was taken to a hospital Friday afternoon to be evaluated for drug use or any mental issues.
Police say he could face carjacking and felony hit-and-run charges.
Authorities say witnesses told officers he exited a vehicle after the first crash, took off his clothes and carjacked another vehicle. They say he was screaming at the top of his lungs.
Police say four people were injured in the second crash including a pregnant woman who was almost full term and broke both her legs.
