ST. THOMAS, Ont. - Provincial police say a St. Thomas, Ont.-area man who photographed young female models and weddings is to appear in court Tuesday on child sexual exploitation charges.

Police say they were contacted by U.S. investigators about a man communicating via the Internet with a person in Colorado.

The investigation revealed the person was allegedly sexually abusing children in Ontario.

Police say the investigation was carried out with the help of Toronto police, Colorado Springs police and the U.S. Department of Homeland Security.

Last week, investigators raided a home in Southwold Township, just West of St. Thomas, and seized computers and external media devices.

Jason Leonard Sawyer, 31, who operated Jay Sawyer Photography, is facing sex and child pornography charges.
