A Bellevue resident found what police believe was a live grenade from World War II while going through their deceased father’s attic on Monday.

Bellevue Police Ofc. Seth Tyler said police first responded to the home on the 16500 block of Northeast First Place, but later called the Army to assist.

“We had a bomb technician go out to the house, take a look at it and decide it was probably still a live grenade,” Tyler said, “so we contacted the Army at JBLM (Joint Base Lewis-McChord).”

An explosives disposal team contained the grenade and returned it to JBLM for disposal, Tyler said, adding found grenades occur 1-2 times a year in the city.

“Usually they end up being inert,” he said, “meaning the explosives had been drilled out.”
