CLARKSVILLE, Tenn. (AP) - Federal, state and military officials are investigating the discovery of about 100 pounds of explosives in Montgomery County.

Ted Denny, a Montgomery County Sheriff's spokesman, said two hunters discovered the C-4, a plastic explosive, on residential property out in the county late Sunday evening.

Denny said it appears the explosives are military ordnance, so officials from nearby Fort Campbell as well as the Bureau of Alcohol, Tobacco, Firearms and Explosives were also investigating.

Denny said authorities are talking to a person of interest in the case but no arrests have been made yet.
