TWENTYNINE PALMS, Calif. (AP) — A person who was surrounded by military police responding to reports early Tuesday of an active shooter on a California Marine Corps base sustained a self-inflicted gunshot wound and was transported to a medical facility, military officials said.

Shots were reported around 6:30 a.m. at Marine Corps Air Ground Combat Center Twentynine Palms, 125 miles east of Los Angeles, Capt. Nicole Plymale said.

Military police cordoned off the area and were communicating with the person when the individual sustained the gunshot wound about two hours later, Plymale said. No one else was injured. A shelter-in-place order was lifted by mid-morning and the gates to the base reopened.
