A bomb threat to Naval Base San Diego prompted the temporary lockdown and search of the area, U.S. Navy authorities said. The threat is similar to previous threats.
The note, found in a portapotty at approximatrly 1 p.m., prompted authorities to lock down Pier 7, said Brian O'Rourke, a media relations officer for Navy Region Southwest.
Officials combed through USS Essex but did not find anything. As of 2:26 p.m., authorities say they are standing down on their search.
No injuries have been reported.
O'Rourke said the note was similar to previous reported threats. Officials with Naval Criminal Investigative Service and BAE Systems are offering a $5,000 reward for information leading to an arrest in a series of a dozen false threats made on local military facilities and shipyards.
NCIS officials say various threats - first received in November 2015 - have caused work stoppage to maintenance and repair work being conducted on U.S. Navy ships. The first threat was written inside a portable toilet on a ship at the NASSCO shipyard on Friday, Nov. 6, 2015.
