BENBROOK (KRLD) – Western Hills High School in the Fort Worth Independent School District was placed on lockdown Friday morning after reports of a student with a gun on a bus.

The weapon was described as a semi-automatic handgun.

Authorities searched the campus and were able to locate the student, said Fort Worth ISD spokesman Clint Bond. Police also found the gun, but did not say where that weapon was located. It was not loaded.

The Benbrook Police Department arrested the student and charged him with possession of a firearm on school property.

He was taken to the Tarrant County Juvenile Detention Center.

The lockdown lasted about 20 minutes, but it did not interrupt classes. Things have since returned to normal at the school.
