SAN ANTONIO (AP) — After bats were discovered in a basic training dormitory at a San Antonio Air Force base, military officials are sealing up any potential access points in the building and testing one of the bats for rabies.

The U.S. Air Force Joint Base San Antonio said in a news release Sunday that bats have been seen in the dormitory at Joint Base San Antonio-Lackland over the past week and a half.

Two bats were captured and released into a remote area and one was captured Friday night and will be tested for rabies.

No evidence of nesting has been discovered. The facility is being monitored for bat activity.

The release says that while no trainees have reported being bitten, the Air Force is immunizing any trainees who may be at risk.
