Explosives found in vehicle at Army base in Ga.

FORT GORDON, Ga. (AP) - Authorities say a man was arrested after explosives were found in a vehicle on an Army base in Georgia and the FBI is investigating.

A spokesman for Fort Gordon near Augusta said Wednesday military authorities are not treating the case as a terrorist threat.

Spokesman Buz Yarnell gave few other details. A news conference was scheduled at Fort Gordon later Wednesday.

Yarnell said a search of the civilian's vehicle Tuesday uncovered a knapsack containing military hand grenades. He said the man arrested is a suspect in a theft of military equipment from Fort Gordon in April.

FBI spokesman Steve Emmett in Atlanta said federal charges are forthcoming but he does not expect them to involve explosives or terrorism.
