Police in Kawaguchi, Saitama Prefecture, have arrested seven 17-year-old youths over the attack on five other youngsters who had been riding bikes and listening to music last October.
The assailants violently punched and kicked the boys, and then stole two of the bicycles before fleeing the scene, TV Asahi reported. One of the victims sustained a fractured skull and was sent to the hospital in serious condition.
According to police, the seven assailants had claimed to be "hunting those without a license" after they explained to their victims that "playing music without a license in Kawaguchi was illegal," and that because the five boys had no license, they must be reprimanded.
The boys who had been attacked were able to provide police with a description of their attackers.
Police quoted some of the suspects as saying they had never intended to kill anyone.© Japan Today
