Authorities say they have lifted a lockdown at a U.S. Army Reserve training facility in Northern California after determining reports of an intruder were unfounded.
The Alameda County sheriff's office says all is clear at Camp Parks Reserve Forces Training Area in Dublin, 35 miles east of San Francisco.
Law enforcement agencies swarmed the U.S. Army Reserve facility Tuesday morning after police received a report of a possible shooter on the sprawling complex.
No shots were reported.
