Spokane law enforcement, the FBI and a disposal team are investigating an explosive device that detonated around 4:30 a.m. on Saturday in the 5800 block of North Monroe Street.
There were no injuries in the blast. Federal authorities were brought in according to standard operating procedures, police said.
The device was placed under a car in a residential area. Most of the damage was confined to the vehicle.
Authorities do not believe the incident is related to this weekend’s Hoopfest celebration downtown. The investigation is continuing.
