Some guy's attempt to siphon gas from a U-Haul truck in Portland, Oregon went awry went the fuel caught fire.

"All you see is fire ignite and then you see this guy run away with the lower half of his body in flames," Lt. Rich Chatman said.

Surveillance footage shows the truck bursting into flames and the failed thief can be seen running down the street with his pants on fire. Authorities are still looking for the suspect.
