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.
