A custodian found a live improvised explosive device in a restroom at Bush Airport on September 11, 2026, setting off a police response and searches across the airport. The discovery came on the 25th anniversary of the 9/11 attacks.
The custodian was emptying a waste bin beneath a sink in the men’s restroom near Gate D2 at about 4:30 p.m. He left the room and alerted airport officials, who called the Houston Police Department. The device was small, but its contents raised the stakes.

It consisted of a red cardboard tube about 4 inches long and 1 inch in diameter, with a fuse attached. Bomb technicians used X-rays and found powder inside that had not yet been identified.
Testing later detected a potassium chlorate mixture. The technician described it as “violently energetic.”
The technician wrote that ignition would cause “a loud report, smoke, and a pressure wave as the container ruptured.” The conclusion: “By definition, this would be an improvised explosive device.”
An initial firecracker label preceded the bomb squad call
The first police call slip described the object as a “cheap firecracker.” A sergeant advised an officer to take it to Houston Fire Department Station 63, but a captain there refused to accept it, citing the danger to the station, and requested the bomb squad.
A bomb technician collected the object in a nearby field and drove it to the department’s tactical operations building, about 20 minutes away. The technician later examined it there.
Aviation-security expert Larry Wansley said the officer responding at the airport should not have handled or removed the device from the terminal. He warned that doing so could have had “catastrophic” consequences.
Search instructions took more than six hours to reach airport authorities
More than six hours passed between the discovery and clear instructions to airport authorities about which areas to search. Explosive-detection dogs then swept Terminals A through E, baggage-claim areas, the underground train tunnel and loading-dock dumpsters.
The searches found no other devices. The operation covered both passenger areas and places used to move baggage and supplies.
Video review narrowed the time window, but not who placed it
Investigators reviewed surveillance footage and found that the custodian had first cleaned the restroom at about 2:06 p.m. He told them he had emptied the same bin earlier in the day. That left open whether someone placed the device after that cleaning or whether it went unnoticed then.
The Houston Airport System referred questions to the police department. The agency said its investigation remained ongoing and described its approach to reviewing the response:
“HPD takes incidents involving our airports seriously and continually reviews our response to ensure our procedures are safe, effective and efficient.”
