Suspicious vehicle prompts lockdown at Fort Sam Houston

A suspicious vehicle prompted a lockdown at Fort Sam Houston in Texas Sunday evening.

The lockdown began at approximately 5:30 p.m. local time and was lifted nearly three-and-a-half hours later. Alex Delgado, spokesman for the 502nd Air Base Wing, says in a statement that the lockdown was lifted Sunday night after officials decided it was safe to return to normal operations.

Delgado said the driver of the vehicle was taken into custody. It was not immediately clear how long the driver would be held or whether charges would be filed. No one else was in the vehicle.

According to the city of San Antonio's website, the base was established in 1910 -- the ninth-oldest Army installation in the country. Fort Sam Houston now encompasses 3,000 acres and is home of military medicine and part of Joint Base San Antonio.
