The U.S. Marine Corps Air Ground Combat Center in California was placed on lockdown Monday amid reports that shots were fired, officials say.
"We have received reports of shots fired on board MCAGCC," reads a tweet posted by Combat Center officials Monday morning. "The MCAGCC Provost Marshals Office is currently responding to the situation. The installation has entered a lockdown state and all personnel are required to shelter in place."
Later on Monday afternoon, the lockdown was lifted.
“At this time, we can confirm that a weapon was inadvertently discharged," Marine Capt. Zachary Colvin added. "No injuries have been reported. This incident is under investigation."
