San Antonio police have arrested a gunman in a shooting at Fort Sam Houston.
A San Antonio police officer says police arrested a gunman Monday afternoon and turned him over the military authorities. The officer was speaking anonymously because the person was not authorized to speak to the media.
Kathy Salazar, a staff member in the base public affairs office, said the Fort Sam Houston was on lock down. She could not immediately offer additional details.
A San Antonio television station showed one person taken away in an ambulance, but it was not immediately clear who was injured or how.
The base includes the U.S. Army's top hospital and the headquarters for its North America Command.
