According to police, bomb dogs detected possible explosives in three separate cars at the airport parking garage. The city sent fire and HazMat crews to the airport to investigate. Buses shuttled people from the terminals to an undisclosed shelter. Flights to and from the airport have also been delayed, and San Antonio officials asked that people steer clear of the area. By 4:30 p.m. local time, the airport reopened and 2,000 passengers returned to the terminals. No suspicious packages were found after cars were searched, and the parking garage reopened at 6:30 local time.
