SAN ANTONIO - Some travelers saw a large presence of San Antonio Fire Department personnel at the San Antonio International Airport on Saturday as crews inspected a box left behind in a rental car.
The department's hazmat unit was called to the car rental building at the airport around 4:15 p.m. after someone left a container typically used to store medical samples in a rental car, which sparked concern.
Officials said the box initially appeared to be a biohazard, but it turned out that there were no medical samples inside the container.
Three San Antonio fire units were seen parked near the airport terminals.
