A US man went on a naked hijacking spree, causing a string of accidents, according to reports.

Police say John Brigham was involved in a car accident in Scottsdale, Arizona on the weekend. After the crash, Brigham apparently stripped naked and jumped onto the roof of a Honda CR-V.

From there, he jumped down and hijacked a Toyota Prius. Brigham then reportedly caused a five-car pile-up further down the road, hitting a pregnant woman driving a Lexus. From there, he reportedly collided with a Chevrolet head-on, bringing an end to the rampage.

According to reports, Brigham was attempting to break into other vehicles on the road when police finally pitched up. After being arrested, he was taken to a local hospital to be treated for a number of injuries. He is set to face charges for hijacking, robbery and leaving the scene of an accident.

Seven people were hospitalised thanks to Brigham's run of destruction.
