(CNN) -- An airman armed with a handgun barricaded himself inside a building at Schriever Air Force Base in Colorado Springs, Colorado, base officials said in a statement Monday.
No shots had been fired and no injuries reported, according to a spokeswoman at the base's public affairs office.
The airman, assigned to the base's 50th Security Forces Squadron, was barricaded inside a building where personnel get paperwork and equipment before being deployed, according to the base. No weapons are normally stored in the building, the spokeswoman said, but the airman was armed with a personal handgun.
The building was evacuated and law enforcement units had responded, said the statement posted on the air base's website.
"Our first responders are trained to handle situations such as this and we are working with our community partners to resolve this situation as quickly and safely as possible," Col. James P. Ross, 50th Space Wing commander, said in the statement.
No operations on the base were immediately affected, according to the base, which is home to the 50th Space Wing, the unit responsible for satellite command and control for the Department of Defense.
