A 17-year-old student was injured in a knife fight in Pendik, Istanbul, after a dispute between pupils escalated into violence, police said. The incident took place in the Yenişehir district at around 15:00, when two 17-year-old students, identified as G.C. and S.E.T., clashed at Hezarfen Vocational and Technical Anatolian High School over an argument described as “side-eye.” The confrontation flared again when the students faced each other after school, about 500 metres from the school. During the fight, G.C. was stabbed. The wounded student walked to the schoolyard. A duty police officer was alerted and contacted medical and police teams. Paramedics provided first aid and determined that G.C. suffered minor injuries to his ribs and hand. He was taken by ambulance to Marmara Training and Research Hospital, where treatment was completed and he was discharged. Pendik Public Security Directorate Asayiş Bureau officers launched an investigation and detained four suspects they linked to the incident. Police took into custody 14-year-old Y.E.T., 17-year-old S.E.T., who police said had a knife, and two other youths, 17-year-old H.S. and 15-year-old T.Ö. Authorities also detained the four suspects with knives allegedly used in the attack. The investigation was ongoing as they carried out further checks on the case.
