Lexington police say construction workers renovating a home found a grenade in the backyard.

Officers responded to the scene, and the department's Hazardous Devices Unit took x-rays to find out the grenade was a live ordinance.

A robot placed the grenade in a containment vessel and removed it from the scene. It was later detonated in a controlled location.

Officers say the grenade was likely in the ground for an extended period of time, and there were no other explosives found in the area.
