The USS Carter Hall, a Navy ship docked near Norfolk, Va., was on lockdown Thursday after an active shooter was reported on a nearby barge in the shipyard, according to a local report.

"Police are investigating a report of an active shooter at 2 Harper Ave. Dispatch received the 911 call at 1146am. No further information at this time," the Portsmouth Police Department wrote on Twitter Thursday afternoon.

The Navy issued a statement this afternoon that said the ship's security team was unable to find the shooter, a weapon, or shells that would have indicated someone had fired a gun, the Virginian-Pilot reported.

The local police also said they had not found any victims, according to the Navy's statement. Portsmouth police did not comment on social media beyond their initial statement around noon.

The USS Carter Hall has been moored in the General Dynamics shipyard since January. It sits next to a barge with housing for sailors and offices.

The ship's home port is Joint Expeditionary Base Little Creek in Virginia Beach, a few miles south of Portsmouth. It was most recently on a deployment to Europe and the Middle East in September 2017.
