US: Toy grenade causes bomb scare in Houston airport

A toy grenade in a passenger's bag forced the shutdown of a security checkpoint at Houston's William P. Hobby Airport Thursday morning, just a day after the international terminal of the city's other major airport was evacuated due to a bomb scare. Houston Airport System spokesman Bill Begley said people were allowed to approach the checkpoint again after a bomb squad determined that the suspicious item spotted by a TSA agent was a "novelty grenade." Hobby Airport is a hub for Southwest Airlines. The website FlightAware indicated delays of an hour or more for flights arriving and departing the airport immediately after the security checkpoint reopened. An AP journalist was in the line when a TSA agent raised the alarm at about 4:35 a.m., forcing hundreds of people to move away from the immediate area on both sides of the security checkpoint.<br/>
