The main gate at Joint Base Andrews was on lockdown Thursday evening after a woman walked onto the base and claimed she had a bomb, the Air Force base said.
About 5:15 p.m. Thursday a woman walked into the Visitor Control Center at the base and said she had a bomb strapped to her chest, Joint Base Andrews tweeted.
Emergency responders arrived and the woman was apprehended, the base said. An Explosive Ordinance Disposal team found the woman had no explosives.
Joint Base Andrews said the situation has been diffused and emergency personnel secured the area. The main gate reopened about 9 p.m., the base said.
"Fortunately, this incident was diffused quickly and was determined to be a false-alarm,” said Col. Brad Hoagland, a JBA commander.
The base said its missions were not impacted and there was no impact to traffic on Allentown Road, residential property or businesses in the area.
Offiicals advised all personnel and residents to avoid the area until further notice.
