Rochester, MN (KROC-AM News) - A Rochester man was arraigned in Olmsted County court Friday morning on charges stemming from a child pornography investigation.

The criminal complaint against 60-year-old Mark Bunce lists 10 felony counts of possession of pornographic work. The complaint states the investigation was opened in May after his Bunce's wife called police and reported her husband had been acting strangely and that she had discovered suspected child porn on his computer.

A search warrant was later executed and investigators later found hundreds of videos and thousands of child porn images.

Bunce's conditional bail was set at $10,000 and he was ordered to return for another court appearance on July 11th.
