LEXINGTON, Ky. (FOX 56) — A Lexington teacher is now facing federal charges involving the sexual exploitation of children.

Kevin Lentz, a former teacher at Henry Clay High School, was arrested last week and accused of exchanging pornographic images with a 9-year-old boy.

Investigators said Lentz convinced the child to send him pictures of his private parts and asked the victim to delete their conversations so his parents wouldn’t find out. According to court documents, 85 images of pornography were sent using the phone.

He’s facing federal charges for producing child porn and enticing a minor to engage in criminal sexual conduct.

Lentz was placed on administrative leave by Fayette County Public Schools.
