Moscow police responded to a report of a suspicious device believed to be an explosive at about 2:15 p.m. at the Robinson Mobile Home Court.
The Spokane Bomb Squad arrived on scene at about 5:30 p.m. and destroyed the device, which appeared to be a pipe bomb.
Some residents were evacuated from the court but no one was injured.
Moscow Police Department Capt. Roger Lanier said a maintenance worker reportedly discovered the device, which was similar to a “big M-80 wrapped in electrical tape with a fuse,” inside a residence.
The investigation is ongoing.
