Police in Oklahoma City are investigating how a grenade wound up in a residential yard.
Authorities say a homeowner on the city's southeast side was doing yard work when he noticed what appeared to be a grenade in the yard of his neighbor about 2:30 p.m. Saturday.
The Oklahoma City Police Department Bomb Squad responded to the homeowner's call but could not immediately determine if the grenade was potentially explosive or inert.
Officials say bomb squad personnel decided to take custody of the grenade and dispose of it on the police firing range.
There were no reports of injuries. It was not immediately clear why the grenade was in the yard.
