DES MOINES, Iowa (AP) -

Federal officials say an allegation that a border officer drew and pointed a gun at a Boy Scout from Iowa appears to be unsubstantiated.

The Department of Homeland Security's Office of Inspector General says security footage and interviews helped officials investigate the claim.

The Iowa troop was stopped July 7 at the Alcan Port of Entry in Alaska. A scoutmaster later claimed some Scouts witnessed a Customs and Border Protection officer point a gun at a Boy Scout.

Officers present denied drawing a weapon. Federal officials say officers searched one of the troop's vehicles after a personal camera used to take prohibited photos of the port indicated marijuana possession. The search turned up nothing.

The Office of Inspector General says at least $19,000 was spent investigating the case.
