Not knowing whether the grenade was live or dangerous, the resident called police at about 2 p.m. Saturday. He was driving in his car with the grenade, and police advised him to pull over immediately, according to the police report.
York notified the Maine State Bomb Squad and a local officer and Sgt. Chris Harriman from the bomb squad met the resident in an open area behind the Meadowbrook Plaza on Route 1.
Harriman took the grenade back to the squad's headquarters in Gray, where experts didn't determine whether it was live or not, he said. They took no chances, detonating the grenade with explosives.
What's unusual about the incident, according to Harriman, is that it happens all the time.
"World War II memorabilia, we get them all the time," he said Wednesday. "We get close to 50 (calls) a year. Everything: Grenades, mortars, bomb fuses, rockets..."
