A student at Heritage High School in Colleyville was arrested Thursday afternoon after he was caught with an unloaded handgun and ammunition in his backpack, police said.
The student, a 16-year-old boy, faces a third-degree felony charge for possessing a weapon in a prohibited place.
Earlier in the day, school administrators “had reason to believe there may have been a student with a gun on campus,” Heritage Principal Lance Groppel wrote in a letter to parents.
At about 2:45 p.m., a school police officer searched the student’s backpack and discovered a .45-caliber semiautomatic handgun, police said.

The officer confiscated the weapon, which belonged to a family member of the student.
“Campus and district administrators believe this to be an isolated incident,” Groppel’s letter said.
No threats were made by the student, police said. His name and photo are not being released because he’s a juvenile.
