A 46-year-old Davenport man is charged with assaulting a man in front of Scott County District Court and then chasing him through the front door of the courthouse and into the security area.
Jimmy Lightner has pleaded not guilty to willful injury causing bodily injury and going armed with intent, according to court records updated Tuesday. He was in custody Tuesday at the Scott County Jail.
Both charges are Class D felonies that carry five-year prison terms upon conviction.
He's also charged with interference with official acts causing bodily injury, an aggravated misdemeanor punishable by two years in prison.
Peter Bawden, a Scott County Sheriff's detective, said six corrections officers and bailiffs had to detain Lightner as he tried to dart through the metal detector after the victim. He was found with a 5-inch blade duct-taped to his forearm, Bawden said.
Lightner, who didn't know the victim, also had a pocket knife, Bawden said.
Courthouse surveillance video shows Lightner standing in front of the courthouse's front door as the male victim and a woman approach. Lightner then attacks the victim and chases him into the courthouse.
A surveillance video inside the security area shows Lightner still chasing the victim through the metal detector, when he's stopped by courthouse security officers.
