A tear gas grenade found at a construction site Thursday afternoon was later detonated at a former Madison County landfill, Richmond police said.
The explosive device was found after 5 p.m. Thursday on a lot on Douglas Court, Richmond police spokesman Sgt. Willard Reardon said. The area was secured until a Kentucky State Police bomb squad could arrive to remove the device from the scene.
"They put it in some kind of packing and they took it out to a landfill in an isolated area and detonated it," Reardon said. "The bomb guy said it was like a tear gas-type grenade that apparently had been there for some time."
No one knows how the grenade came to be on the vacant lot, Reardon said. No other devices were found.
The detonation site was on an old city landfill on Four Mile Road where the police now have a firing range, Reardon said.
