SEATTLE-A man who deliberately set a pickup truck on fire has been arrested.
Officers responded to reports of a truck fire in the 11300 block of Corliss Avenue North shortly before 11 p.m. Saturday. 
Investigators say that three adult males and an adult female were gathered around the victim's vehicle, a 2002 Chevrolet pickup truck. The adult male suspect and adult male victim got into an argument over the female.  The suspect brandished a firearm and then squeezed a container full of an unknown accelerant into the pickup truck and lit it on fire.  The suspect and female then fled the scene on foot.
The victim, a 28-year-old male, retrieved a fire extinguisher from a nearby resident and tried unsuccessfully to put out the fire before running off.
Fire department personnel responded to the scene and put out the vehicle fire. Besides destroying the truck, the fire also damaged some electrical wires hanging above the truck.
Officers later found and stopped a suspect vehicle, a Dodge sedan, at North 115th Street and Aurora Avenue North. 
Both the primary suspect, a male in his 20′s, and the female from the original group of four were in the vehicle. 
The suspect was placed under arrest and both he and the female subject were transported to the North Precinct to be interviewed.
Seattle Police Arson/Bomb Squad detectives responded to the scene and are handling the investigation.
