Travis AFB lockdown lifted: No shooter found

Officials at Travis Air Force Base in Fairfield lifted a lockdown Wednesday afternoon after responding to reports of gunshots but finding no shooter, authorities said.

Emergency personnel at the base ordered the base locked down around 3:30 p.m. in response to reported gunshots at the base exchange, officials said. The lockdown was lifted shortly after 5 p.m.

Officials at the base had earlier warned people to lock their doors and windows and shelter in place in response to “a real world security incident.”

The incident took place the same day the base was scheduled to conduct a security exercise, but authorities said the situation was unrelated to the drill.
