June 7 (UPI) -- A Boy Scout with a toy grenade caused William P. Hobby Airport in Houston, Texas, to shut down Thursday morning, airport officials said.
Law enforcement closed off a 200-foot radius in the area after they said they found the item in the 17-year-old's bag around 4:30 a.m.
Airport officials said they temporarily evacuated the airport and reopened by 5:30 a.m.
"Expect some delays through security, and as always check with your carrier to see if your flight has been impacted," the airport said in a tweet.
A Houston police officer told KXAN-TV in Houston that he was told the grenade was going to be used to teach a class about what not to take to the airport.
Police said they didn't know whether charges will be filed against the Scout, who they initially detained for questioning.
The issue caused 12 Southwest flights and one Delta flight to be delayed.
On Wednesday, Houston's other airport, George Bush Intercontinental Airport, was temporarily shut down for a suspicious device investigation after an impatient man claimed he had an explosive device in his bag. No device was found.
