Nine teenagers were arrested after a fight broke out at an unauthorised gathering on Clapham Common that was promoted on TikTok, the Metropolitan Police said.
A 17-year-old boy was stabbed during the disorder and taken to hospital with injuries described by police as neither life-threatening nor life-changing. Officers were called to the south London park on Friday, 22 May, as fighting erupted in the crowd. Footage from the scene shows people punching one another and attacking individuals on the ground while officers attempt to break up the group.
Of the nine people taken into custody, four boys – aged 16, two aged 17, and a 19-year-old – were arrested on suspicion of affray. A 16-year-old and a 14-year-old were arrested on suspicion of grievous bodily harm and affray. A 20-year-old man and a 15-year-old were arrested on suspicion of possessing a knife, and an 18-year-old was arrested on suspicion of assaulting a police officer. All remain in police custody.
The Metropolitan Police said a police presence will remain in the area while CCTV and other evidence is reviewed. Anyone with information is asked to call 101 quoting CAD8948/22May.
Social media‑fueled gathering
The gathering was promoted on TikTok as an alleged music event, part of a growing trend in which large groups of young people organise so‑called “link‑ups” online and converge on public spaces within hours. The Metropolitan Police have previously warned about the speed and scale of such events, which are often advertised publicly on platforms including TikTok and Snapchat, and can quickly spiral into violence.
The incident on Clapham Common follows a similar pattern to disorder seen on Oxford Street in August 2023, when nine people were arrested after a TikTok rumour of planned group crime prompted 34 dispersal orders. Police have said that viral trends and public posts on social media are a driving force behind such gatherings, which have been described as a “swarming” phenomenon.
Previous disorder in Clapham
Friday’s stabbing comes just weeks after a similar large‑scale gathering of teenagers on nearby Clapham High Street in late March and early April. Hundreds of youths flooded the area after schools emptied for the Easter holidays, forcing shops to close early and leaving families and passers‑by barricaded inside stores. Footage from that event showed fires being lit and fireworks being set off on Clapham Common.
Police deployed around 100 officers to disperse the crowd. Several arrests were made, including three teenage girls – a 17‑year‑old and two 13‑year‑olds – arrested on suspicion of assaulting an emergency worker on Tuesday, 31 March. Three other girls, aged two 16‑year‑olds and a 15‑year‑old, were arrested on suspicion of shoplifting and assault on Saturday, 28 March. Shopkeepers reported being forced to lock their doors and expressed concerns about damage to businesses.
The Metropolitan Police have repeatedly urged parents to take responsibility for knowing their children’s whereabouts and online activities, and have acknowledged community concerns about the pattern of disorder. The force said it will continue to review evidence from Friday’s incident and maintain a visible presence in the area. Anyone with information should call 101 quoting CAD8948/22May.
