An unconfirmed report of shots fired at the Naval Medical Center San Diego this morning, prompted law enforcement authorities to swarm the building.

The report of an active shooter in the basement of building 26, a combination gym/barracks, which houses the Security Pass and Decal office, was made around 8:15 a.m., according to Naval Medical Center San Diego.

Shortly after 9 a.m., the entire complex had been secured, according to Navy officials, with no casualties reported.

Roosevelt Middle, San Diego High School and Garfield High School were all put on lock down as precaution, however all students and staff are reported to be safe and the lockdown has since been lifted.

Navy Public Affairs are not confirming at this stage, a CBS News report, claiming a person had been detained inside the medical center off Bob Wilson Drive.
