A 25-year-old southwestern Illinois man has been charged with producing and distributing child pornography.

Madison County Sheriff Robert Hertz says Steven Yon was charged Thursday with one count of producing child pornography and five counts of disseminating child pornography.

Authorities say one metro-east child was identified in connection to the production of child porn. They say investigators and social services ensured that the child is safe.

Authorities continue to investigate. They say they've found no other evidence suggesting other local children were involved.

Yon was being held in the Madison County Jail on $250,000 bond. It wasn't immediately clear if he has an attorney.
