U.S. Marine Corps Base Camp Pendleton in North San Diego County was back open after a suspicious package prompted a lockdown Wednesday morning.
The package was found outside Camp Pendleton’s main gate near Harbor and San Rafael drives before 3:15 a.m., when Oceanside police said they were first called. It was not immediately disclosed why the item caused a concern.
Oceanside police said all gates from Interstate 5 onto the military base were closed due to the investigation, but the U.S. Marine Corps said the closure was only affecting the base’s main gate.
