LONGMONT, Colo. (AP) _ An Army Reservist's plans for a high-powered tennis workout have ended with the confiscation of a grenade launcher by police.

The 66mm weapon was taken from Armen Michael Melikian, an infantryman in the U.S. Army Reserve, by officers who spotted it last week while taking a damage report at a nearby home, police said.

Melikian told police he brought the weapon home from basic training at Fort Benning, Ga., last summer because it was no longer rigged to launch grenades, and he wanted to launch tennis balls with it.

The Army said the hand-held cardboard and fiberglass weapon is worth about $2, according to Longmont police Officer Linda Lewellen. There are no plans to prosecute Melikian, she added.

However, an army officer will pick up the device, and it probably will be destroyed, she said.
