FAYETTEVILLE, N.C. -- Officials at Fort Bragg say an investigation is under way into the disappearance of nearly 14,000 rounds of ammunition at the Army base.

Staff Sgt. Joshua Ford, a spokesman for the 82nd Airborne Division, says the ammunition went missing from the 1st Brigade Combat Team at Fort Bragg.

The Fayetteville Observer reports that Ford believed the ammunition was taken overnight on Tuesday. The 1st Brigade team was placed on lockdown for a few hours Wednesday night while officials conducted a search.

The missing ammunition can be used in an M-4 or M-16 assault rifle.

Ford says the 82nd Airborne Division and military police are taking the matter seriously and that "any amount of ammunition that goes missing" has "got to be accounted for."
