TRIGG COUNTY, Ky. (WKRN) — A road was shut down in Trigg County for several hours on Sunday following the discovery of a grenade in the river, which was destroyed using an explosive.

According to the Trigg County Sheriff’s Office, the road was closed at the bridge on South Road/Highway 139 between Main Street and U.S. 68/Kentucky 80.

Authorities said somebody was magnet fishing off the bridge when they retrieved the unexploded ordnance — which appeared to be an old 40mm grenade — from the river.

Officials announced just after 3:30 p.m. on Sunday, Dec. 4 that a bomb squad was being dispatched to safely dispose of the ordnance, adding that all precautions are being taken.

Then, at 5:52 p.m., the Cadiz Police Department posted a statement about the incident on Facebook, which said, in part, “Fort Campbell EOD is on scene, assisting in the removal of the device. They are working diligently to safely remove the device from the area. It is possible that the device will be ‘destroyed in place’ if it is determined it can’t be safely moved. The area EOD is working in is free of businesses and residences, so there is no need for any closures or evacuations.”

As of 6:25 p.m., the device has been safely removed and the road has been reopened, according to authorities.

However, police provided some clarification about the circumstances surrounding the incident on social media:

We are seeing comments about an explosion, and that many believed is was too large to be the 40mm grenade we previously posted about. To dispel any rumors and to answer questions, this is what occurred:

The grenade was not stable enough to be moved, due to its time in the water, so EOD decided it was best to “destroy in place.” As a result, they placed their own explosive on the grenade, and set it off. That is why the explosion seemed more powerful than what a 40mm grenade should be.

Thank you to Fort Campbell EOD for their assistance in removing this device, and thank you to the individuals who fished it out to begin with. Contacting the police and allowing for proper disposal of the device kept everyone safe.
