HOUSTON—A man who taught a filmmaking class at an elite private school in Houston is facing child pornography charges.

Investigators arrested Thomas Edward Kelley, a former teacher at the Kinkaid School in West Houston, on Wednesday.

He was arrested after authorities received a tip.

“We received information that the individual was trading child pornography through yahoo e-mail accounts,” said Harris County Assistant DA Eric Devlin.

Prosecutors say hundreds of child pornography images were found on Kelley’s home computer.

The immediate concern was whether any Kincaid students were victims.

“We did not see anything to indicate that it was a student we actually looked very hard at that because we were so concerned that he was a teacher,” said Devlin.

Kelley has been charged with two counts of possession of child porn.

Bond was set at $20,000 per count, which Kelley was able to post.

TEA records indicate Kelley was became a Certified Educational Aide in the State of Texas in 1984.

In a statement released Thursday, Kinkaid Headmaster Donald C. North confirmed that Kelley was employed at the school, but said he was dismissed on March 3, 2009, once school officials learned about the criminal investigation.

North said Kelley was a part-time teacher. He was hired in August of 2006.

“School administrators spoke privately with filmmaking students at Kinkaid and communicated with their parents about this matter, and we are confident that nothing inappropriate occurred in the filmmaking classes or with students,” North said in the statement.
