(KNZA)--A Hiawatha man has been arrested on a pair of child sex charges.

30-year-old Robert Alan Edwardson was arrested Tuesday by the Hiawatha Police Department on a Brown County warrant for two counts of aggravated indecent liberties with a child.

Brown County Attorney Kevin Hill told MSC News that the charges involve two separate victims, one between 14 and 16 and the other under 14.

The charges were filed last week following an investigation by the Police Department.

Edwardson made his first appearance in a Brown County courtroom Thursday afternoon.

A preliminary hearing was set for Wednesday, February 20.

Edwardson remains in the Brown County Jail, held on a $75,000 bond.
