Fond du Lac police say reports of a so-called knock-out game where people are randomly attacked by young people is not something they’re familiar with. Reports have surfaced on the Internet of a game where a group of young people attack someone walking along a sidewalk attempting to knock them out with a single punch. Fond du lac assistant police chief Steve Thiry says he hadn’t even heard of this phenomenon until doing some research. "I did a little research on it yesterday and I've seen some of the articles, including some saying this is an urban myth," Thiry told WFDL news. Thiry says while there are bar fights in Fond du Lac that occasionally spill out onto the street …nothing to the extent of a premeditated attack game.
