A student at an Alief Independent School District high school has been expelled for bringing a gun near the campus.

According to Alief ISD, Edwin Estrada Figueroa and another person got into an off-campus disturbance on Tuesday evening, then Figueroa followed the person onto Elsik High School's campus near the field house.

The person who was being followed flagged down an Alief police officer to report they were being followed, officials said.

That officer stopped Figueroa and asked to search Figueroa's car. The officer found a gun, according to the district.

Figueroa, 18, was expelled Wednesday morning. He's free on $2,000 bond.
