A 17-year-old Ohio boy convicted on charges of attacking and robbing two men as part of the so-called "knockout game" has been sentenced to four years in prison.
Prosecutors in southwest Ohio's Montgomery County say the former Stivers High School student was convicted as an adult of two counts of robbery last month. He and two other teens were charged in attacks on homeless men in Dayton last spring.
Prosecutors say the defendants attacked the victims with the intention of knocking them out with a single punch. The two other suspects, ages 14 and 15, also are charged with robbery.
Police were alerted when a teacher at the school saw a video of the attack on a student's cellphone.
