A National Security Agency police officer opened fire Wednesday morning on a vehicle at an entrance to the intelligence agency's campus in Maryland, law enforcement sources told CBS News. CBS News says three people are hurt and NBC Washington adds that one person is in custody.
The incident, which happened shortly after 7 a.m. ET, is not terror-related, USA officials told CNN.
The White House has been updated on situation and the NSA released a statement saying "the situation is under control and there is no ongoing security or safety threat".
"Our thoughts and prayers are with everyone that has been affected", a White House statement said. The FBI was leading the investigation into the incident.
Nearby, a black SUV with bullet holes through its windshield appeared to have crashed into a concrete barrier at one of the facility's secure vehicle entry gates.
Known as the "Puzzle Palace", the NSA is the nerve center for U.S. electronic espionage as well as the main protector of United States communications and information systems from cyber attack.
A person has been shot outside the National Security Agency's Maryland headquarters.
But in early 2015, two people were shot at by NSA police when they disobeyed orders outside the heavily secured campus. Officials said the driver of the stolen SUV may have mistakenly taken a restricted exit to an NSA security post and ignored police orders to stop, possibly because there were drugs inside the SUV, according to officials.
The incident bears similarities to a 2015 attempted attack by two men who dressed up as women and drove their sports utility auto through the gate.
