The Navy's Explosive Ordnance Disposal team on Thursday removed a World War II-era pineapple grenade that was on display at the Fokai Shop in Tumon.

Store administrator Carlo Dela Cruz told The Guam Daily Post that "a beachgoer" had dropped it off at the store about two weeks ago.

"It was all rusted and everything," Dela Cruz said. "We thought it looked like a cool artifact."

A military service member who happened to walk into the store Thursday saw the grenade. According to the shop, he told store employees, "Hey, did you guys know this thing is still live?"

Dela Cruz said the service member pointed out that there was no detonator on the grenade, so it wouldn't explode, but he advised management to call EOD and have them take it away.

First responders from the police and fire departments arrived at about 12:30 p.m. to keep the public at a safe distance.

The store and the immediate area around it were evacuated for about an hour until the disposal team came for the grenade.

"EOD said there was no danger, unless the building was on fire – and the grenade would probably explode," Dela Cruz said.

The device was safely removed for disposal. The all-clear was issued at 1:36 p.m
