A percussion instructor at Katy High School was fired after students at the school sent out nude photos they found on a cellphone she had lost earlier this year.

Maria Corrales, a Katy ISD spokeswoman, said at least four students distributed the photos, and they will face disciplinary measures, according to the Houston Chronicle.

The school district became aware of the photos on Sept. 15 after parents were told about the photos by a student who saw them.

Campus police are still investigating the incident.

The percussion instructor, who was hired by the school's band booster club, was fired because the nude photos were readily available to students and because of the sensitive nature of the incident, Corrales said.

The photos were "believed to be distributed to quite a few people," Corrales told the Chronicle. "It was not in her best interest to stay there."
