KATY, Texas — A Katy ISD employee has been arrested and charged with possession of child pornography.

District officials sent a letter to parents of Seven Lakes High School students informing them of the incident but did not name the employee in the letter. The district later identified the employee as Bradley Britton, a U.S. History teacher and girls' basketball coach, according to the staff directory.

Katy ISD Police filed the charge of possession of child pornography on a personal device after they obtained evidence Friday.
