Mathew Kowald was cited for disorderly conduct in connection with the incident with his son at their home in Pardeeville, Lt. Wayne Smith of the Columbia County Sheriff's Department said. Pardeeville is about 30 miles north of Madison.

The 36-year-old Kowald was arrested Monday after his wife told authorities about the incident. Kowald was taken to the county jail and held until yesterday, when he pleaded no contest, paid a fine of $186 and was released.

Kowald's wife filed a restraining order yesterday, so Kowald will not be able to have contact with his family, Smith said. Smith said other domestic issues have surfaced, though he wouldn't elaborate.

The boy refused to wear the jersey Saturday, when the Packers beat the Seattle Seahawks in a playoff game, Smith said. Smith said the incident sounded strange when reported at first, but the mother took pictures with her cell phone and that type of evidence is difficult to dispute.

Kowald, contacted later yesterday by the Portage Daily Register, said the incident started as a joke. His son challenged him by saying he wouldn't root for the Packers. When he tied the boy up, the youngster was laughing while his wife took pictures, he said.

"Then he couldn't get out and he got upset and that's it. It lasted a minute," he said. "I didn't mean no harm, and he knows that, but I haven't been able to tell him that."

District Attorney Jane Kohlwey said there wasn't enough evidence to support felony charges.
