Students were taken to the school's football field after the school was evacuated Monday.
KATY (January 14, 2014) Scott Barfield, 19, who was arrested after Seven Lakes High School in Katy was evacuated and searched Monday, appeared in court Tuesday on a charge of possession of a prohibited weapon.
Barfield, who's a student, remained in the Fort Bend County Jail Tuesday in lieu of $20,000 bond.
About 4,000 students were evacuated Monday morning after the discovery of what Katy school district officials initially said was a "potential explosive device."
The building was cleared at around 4 p.m. Monday.
No explosives were found, but authorities did recover a zip gun, a homemade device that could range in quality from a crude weapon to an actual firearm, the district said.
A firearm was also found in the trunk of a student's car, the district said.
The school was evacuated shortly after a scheduled fire drill just after 10 a.m. Monday.
Students were taken to an enclosed area on the school’s baseball and football fields and parents were initially advised not to try to pick up their children.
Just before 1 p.m. the evacuated students were moved to Seven Lakes Junior High stadium and then were released for the day at 1:30 p.m., the district said.
After-school activities were canceled.
The school was locked down Monday evening, but students were permitted to retrieve personal items Tuesday morning.
Officials canceled quizzes and exams scheduled for Tuesday.
