TRAVIS AIR FORCE BASE (CBS SF) — Reports of an active shooter at Travis Air Force in Fairfield Wednesday have been updated to indicate the activity was a false alarm, officials said.

The base had been put on lockdown as of 10:42 a.m. PT, according to the Travis dispatcher, who emphasized at the time it was not a drill, calling it “a real-world situation.”

Fairfield Police and Travis AFB officials later said reports of possible gunshots at the base during a planned drill prompted a response.

Officials at Travis also released a statement, saying that “There were reports of potential gun shots near the Supply Warehouse and therefore, the base immediately responded to ensure the safety of all its personnel, dependents and retirees.”

The statement added that the 60th Air Mobility Wing at Travis is currently “in the middle of a two-day exercise to test and train Airmen on its ability to respond to emergency incidents.”

Earlier Travis had released a statement saying that emergency officials had responded to a “possible real world security incident that occurred during a scheduled exercise.”

Separately about the same time on Wednesday, there was also police activity in Fairfield on the 3300 block of Shenandoah Court, which is about eight miles west of the base. The activity was a standoff involving the US Secret Service as the lead agency along with Fairfield police, according to the US Attorney’s Office, Eastern District of California spokeswoman Lauren Horwood.
