This is the slap that turned this young kid into a killer after he came back to school with a knife and stabbed the other kid

A 15-year-old boy (Arminas) has died from knife wounds after an argument with a younger pupil (Ahmed) escalated at a school in southern Sweden, police reported on Monday afternoon. The older teen was taken to hospital with serious knife wounds after the incident at around lunchtime at a school in the small town of Broby, Östra Göinge. He later died from his injuries. He was allegedly stabbed by a 14-year-old school mate, who was taken into custody while police questioned staff and pupils. "He was cut with a knife, it was serious," Bertil Håkansson, head of security for Östra Göinge municipality, told the TT newswire earlier in the day. According to local newspaper Kristianstadsbladet the incident took place in a corridor at Göingeskolan, a school for pupils aged around 13-15, where the younger teen allegedly attacked the 15-year-old with a knife after an argument between the two boys escalated. "My daughter (…) asked him: 'What have you done?' He said that she should watch herself. She screamed for help. The boy just stood there with a knife in his hand. He stood there like he was paralyzed," the mother of a girl who witnessed the incident told the Kvällsposten tabloid.
