Houston police have detained what officials call an "impatient" passenger at a ticket counter at Houston's Bush Intercontinental Airport whose comments about explosives in a bag prompted the police bomb squad to shut an airport terminal for nearly an hour.

Houston Airport System spokesman Bill Begley says no explosives were found.

He says the unidentified passenger was in line Wednesday morning at the airport's international terminal and made "an inappropriate comment that immediately set off some protocols." About two dozen other people in the terminal were taken elsewhere while authorities examined the man's baggage, then reopened the terminal for normal operations.

No flights were delayed or affected.
