PORTLAND, Ore. (KOIN) — A man was caught on camera trying to siphon gas from a U-Haul truck in SE Portland when his plans went up in flames, according to officials. 

Security guards found the U-Haul truck and a van engulfed in flames around 7 a.m. Monday morning at SE 2nd and Belmont. 

Surveillance video from a nearby store showed a man running from the scene with his pants on fire. 

The security guards called 911 and Portland Fire & Rescue quickly extinguished the flames, but the man seen in the videos had vanished. 

Investigators said the man was trying to siphon gas from the U-Haul using tubes. Fire officials said something went wrong and a fire ignited in a van the suspect was in before quickly spreading to the U-Haul. 

“Something ignited that gasoline caught fire. We don’t believe this is what the individual intended,” said Lt. Rich Chatman with Portland Fire & Rescue. 

Chatman said officials are working to identify and locate the suspect. 

“We assume he’ll probably be needing some kind of medical care for those burns,” Chatman added.
