Two people were taken into custody at a San Diego-area naval base on Thursday after a report of a person with a gun prompted a shelter-in-place warning at the facility, but there were no reports of shots fired or injuries, officials said. Naval Base Point Loma, one of three main U.S. Navy bases in San Diego, went on lockdown and the Naval Criminal Investigative Service and naval security forces responded to the incident, said Navy spokesman Lieutenant Benjamin Addison. A post on the Facebook page for Naval Base San Diego, a separate facility, had warned "all hands" to stay away from Naval Base Point Loma due to a "law enforcement incident." A number of U.S. submarines dock at Naval Base Point Loma, which also has training schools. A representative for the San Diego Police Department could not immediately be reached for comment.
