Katy, TX (CNN) — Authorities found "a potential explosive device" at a Houston-area high school Monday morning after the building was evacuated over fears of an unspecified, perceived threat, the Katy Independent School District said.
Seven Lakes High School in Katy was evacuated after police "learned of a perceived threat on campus" about 10 a.m. CT, and students initially were sent to an enclosed area on the school's athletic fields, the school district's said on its website.
About an hour later, authorities told district officials that a possible bomb was found in the building, according to the district. Details about the device and about the initial threat weren't immediately available.
As of about 1 p.m., a bomb squad still was trying to determine what the suspicious device was, district spokesman Steve Stanford said.
The FBI sent bomb technicians to help the county bomb squad in the case, said Agent Shauna Dunlap, a spokeswoman for the FBI in Houston.
The students were moved to the nearby Seven Lakes Junior High School stadium, and they were expected to be released early in the afternoon, the district said.
Video from CNN affiliate KTRK showed a number of emergency vehicles parked outside the school early Monday afternoon.
