SPOKANE, Wash. -

UPDATE: Spokane Police say an initial investigation indicates the device that exploded was a pyrotechnic-type device, commonly referred to as an M-1000, not a bomb. This appears to be an isolated incident and investigators do not believe there is an ongoing danger to the community.

ORIGINAL ARTICLE: Spokane Police and the Bureau of Alcohol, Tobacco, Firearms and Explosives are investigating a North Spokane explosion that injured one man on Saturday morning.

Just after 1:00 am, Spokane Police responded to a report of an explosion and a collision near the 1200 block of E. Rich Rd. (between N. Morton and N. Perry).

Witnesses described a flash of light and an explosion coming from a Jeep traveling south on Morton. The vehicle left the roadway and came to rest nearby. Witnesses indicated the explosion coming from the vehicle had scattered debris over a half a block.

Officers were on-scene within minutes and located the Jeep, with an adult male driver who had suffered a serious injury to his hand from the explosion. Officers immediately administered first aid, including the application of two tourniquets. The victim was transported to the hospital. Hospital personnel indicated the life-saving measures taken by officers likely saved the man’s life.

Due to the report of an explosion and possible bomb, and to protect the safety of neighbors and others in the immediate area, SPD officers quickly cordoned off the streets surrounding the explosion. SPD’s Explosive Disposal Unit (EDU) utilized the bomb robot to investigate the scene and found further evidence of explosives inside the vehicle. In addition to SPD officers and EDU, ATF, Spokane Fire, and AMR also responded to the scene.

The ATF is the lead agency in this investigation. At this point, no arrests have been made and the ATF investigation is ongoing.
