A grenade found by construction workers in Lexington this week could have been there since World War II, according to Lexington police.
Police said they were dispatched to Rosemont Garden, where construction workers renovating a home discovered a grenade in the back yard. X-rays of the grenade determined that it was live.
A robot used by the police department placed the grenade in a containment vessel to remove it from the scene. It was detonated in a controlled location, police said.
Based on the condition of the grenade, police believe "it had been in the ground for some time." No other explosives were found.
