ST. LOUIS (AP) -- St. Louis police believe that three loosely knit groups are behind several unprovoked attacks.
The attacks are part of what is known as a "knockout game," in which an innocent victim is attacked at random. The St. Louis Post-Dispatch reports that police say participants typically range in age from 12 to 18. The sole motive is apparently the thrill of beating someone to the ground.
Police say some Roosevelt High School students who have been suspended for fighting have been behind several of the attacks.
In April, a 72-year-old man died after an assault near his home. And last week, Mayor Francis Slay and his police bodyguard drove up just after a random attack on a 51-year-old man. The mayor called for help.
