The physique of a 17-year-old highschool boy was discovered at Lake Hamana in Kosai City, Shizuoka Prefecture, and interviews with investigators revealed that the physique had a number of bruises that seemed like he had been crushed. Police imagine that the bruise could have been precipitated when he was assaulted by the suspects, who had been arrested on the twentieth on suspicion of assault, and are investigating the small print of the way it occurred.
