Dirt bike rider's daring US freeway jump investigated

A daring jump over a Los Angeles freeway could land a dirt bike rider in a jam, with authorities investigating the stunt.

Filmed from the ground and the air, Kyle Katsandris' jump over the 60 Freeway in Moreno Valley near LA cleared the four lanes with traffic driving below.

The video posted to Instagram shows a dirt path being prepared to allow Katsandris a clear run-up before the daytime jump.

It is unclear if any of the motorists even noticed the stunt, but it has caught the attention of California Highway Patrol and the Riverside County Sheriff's Department who are now investigating, CBS LA reports.

A man, who called himself a friend of Katsandris, told CBS LA the jump was run-of-the-mill for him but looks more daring because of where it was performed.
