A U.S. Airforce base in Japan was closed for hours Saturday after a suspect entered the base “with a suspicious package.”
Security forces from the 374th Airlift Wing “apprehended [the] suspect who gained unauthorized entry into Yokota Air Base,” a post on the base’s Facebook page announced.
The person was not identified, nor did authorities say what the suspicious package contained, CNN reported.
“Security Forces personnel have since secured the scene and an investigation is ongoing,” the base said.
The shelter-in-place order was issued at 5 p.m. local time and lifted at 8:50 p.m. (6:50 a.m. Eastern time).
“Ensuring the safety and security of Team Yokota is always our top priority,” Col. Douglas C. DeLaMater, commander of the 374th Airlift Wing, said in a news release. “Our security forces’ professionalism and immediate response to this potential threat was outstanding.”
Yokota Air Base is about 35 miles northwest of Tokyo and is home to U.S. Forces Japan and the Air Forces’ 374th Airlift Wing.
