District Attorney Thom LeDoux is requesting a special prosecutor to handle the assault case involving Canon City councilman Colby Katchmar.
LeDoux said he filed the motion because he knows Katchmar well and Katchmar was a contributor to his election campaign.
Katchmar has told colleagues on the council that he is innocent of accusations he assaulted an elderly couple.
According to the Canon City Daily Record, Katchmar and local artist Thomas Lockhart were arrested Thursday night on suspicion of assault and crimes against at-risk adults after a reported altercation with the couple.
Robert Martin and Margene Martin say Katchmar tried to block them from leaving a local business. Police say Margene suffered serious injuries, including a fractured hip.
