A teenager has been stabbed and nine people arrested after an unauthorised gathering promoted on TikTok turned violent on Clapham Common in south London. Police were called to the park on Friday evening (22 May) following reports of large crowds and fights breaking out.
Video footage captured groups of young people punching and grappling on the ground as officers attempted to disperse the crowd. One teenager was taken to hospital with stab wounds, which police described as 'neither life-threatening nor life-changing'.
Nine arrests were made, including four boys aged 16, 17, 17, and 19 on suspicion of affray. A 16-year-old and a 14-year-old were arrested on suspicion of grievous bodily harm and affray, while a 20-year-old man and a 15-year-old were held on suspicion of possessing a knife. An 18-year-old was arrested on suspicion of assaulting a police officer.
Police have urged anyone with information to come forward, and a presence will remain in the area as CCTV and other evidence are reviewed. The incident follows a similar gathering in April when hundreds of youths caused disruption on Clapham High Street, forcing shops to close early.
