Kershaw County authorities have filed additional charges against a man accused of inappropriate behavior with children.

In November, 39-year-old Christopher Yates of Camden was charged with 3rd-degree criminal sexual conduct for allegedly touching a 9-year-old girl inappropriately on several occasions.

At the time, investigators were also checking out another accusation against Yates involving a second child.

Sheriff Jim Matthews says investigators have since gathered evidence of the other allegation, and Yates now is also charged with sending an obscene photo of himself to the cell phone of a 13-year-old girl.
