ABERDEEN PROVING GROUND, Md. (AP) — Army officials say a dog checking a truck at Aberdeen Proving Ground in Maryland alerted for potential explosives, sparking a three-hour closure of one of the installation's gates.
Officials said in a statement Wednesday that while the truck was inspected further, the driver and a passenger were questioned.
The installation's police worked with the Maryland State Fire Marshal's office and Army Explosive Ordnance Disposal to investigate. After about three hours, spokeswoman Heather Roelker says security forces cleared the truck and the installation returned to normal operations.
Aerial images from local television stations showed police vehicles by the Maryland Avenue Gate and a tent set up on the shoulder.
