A Saskatoon man who was one of 12 charged in the province as part of a national child sexual exploitation investigation now faces additional charges of sexual assault and making child pornography.

Russell Dennis Wolfe, 55, appeared in provincial court on the new charges Friday morning.

He's charged with three counts of making child porn and two counts of sexual assault. The offences are alleged to have occurred between Jan. 1, 2001 and Dec. 31, 2004.

Last month, Wolfe was charged with accessing, possessing and making available child pornography.

There are three alleged victims in the new charges, but police are searching for as many as 14 additional victims. They're all girls.

Eleven other Saskatchewan men were charged with child pornography offences, following an investigation by the Saskatchewan integrated child exploitation (ICE) unit.

Wolfe is the only one charged with sexual assault and making child pornography. 

Bail has yet to be decided in his case. His defence lawyer has asked for a bail supervision report to see if electronic monitoring would be an option.

Wolfe will be back in court on July 15.

The charges came after a Canada-wide police probe that focused on people allegedly using file-sharing networks to distribute child sexual abuse photos and video.

Across the country, more than 340 people were arrested last month.
