Parents in Katy I.S.D. got a troubling letter from the district Wednesday, saying the FBI arrested an employee on child porn charges.

Officials say Alan Wayne McNeil, a central office food service employee at Seven Lakes High School, was arrested and charged with possession and receipt of child pornography.

The district says the FBI had been watching McNeil for some time, and evidence seized from his home computer led to his arrest. The district also says McNeil is in the process of being fired.

Authorities say not Katy I.S.D. students are involved in this case.
