Federal authorities are warning people in an eastern Kentucky town that there could be more explosive devices in a wooded area where a man was accused of setting them up.

Authorities found several trail cameras with explosives earlier this month in a wooded area in Harlan County. Police believe Mark Sawaf concealed the explosives in several trail cameras. Sawaf was shot to death by a fire investigator during a confrontation while Sawaf was helping authorities look for the explosives.

Media report the Bureau of Alcohol, Tobacco, Firearms and Explosives issued its advisory Monday, warning people not to touch trail cameras unless they own them.
