LOS ANGELES (AP) — An employee of the Los Angeles County Department of Children and Family Services has pleaded not guilty to charges of possessing and distributing child pornography online.

County prosecutors charged 54-year-old Carlos Enrique Castillo with five counts of sending or receiving obscene matter for sale and a felony count of possessing more than 600 images of child or youth pornography.

Castillo entered his plea Tuesday and was ordered by a judge not to have any unsupervised contact with minors and to not access the internet.

Children and Family Services director Bobby Cagle says in a statement that the alleged behavior goes against its mission to keep kids safe and violates the public trust.

If convicted on all charges, Castillo faces up to eight years and four months in prison.
