CORPUS CHRISTI, Texas (CBSDFW.COM/AP) — A man is in custody at a naval air station in Texas after an “unauthorized person” alert at the base prompted a lockdown.

There are no reports of injuries at the Naval Air Station-Corpus Christi, but the base said Monday morning that the lockdown will remain in effect until the base is confirmed safe.

The base says the facility went on lockdown at about 7 a.m. Monday after an unauthorized person who was possibly armed made it onto the grounds.

In February, a man was fatally shot at the base after he drove through a gate at the Naval Air Station. In that case, the man was driving a vehicle that had been reported stolen and led authorities on a chase before crashing into a barrier at the base’s north gate.
