Mass gatherings of teenagers, often referred to as 'link-ups', are increasingly under scrutiny following incidents in various UK locations, including a notable event in Clapham, south London, in March 2026. Videos and images of hundreds of young people running down Clapham High Street garnered national headlines, prompting debate over the nature of these spontaneous assemblies and their potential for disruption.
While initial reports in March referred to a 'riot' in Clapham, the Metropolitan Police later clarified that there was no widespread looting or criminal damage, despite around 100 officers responding. Witnesses described some teenagers lighting fires and setting off fireworks on Clapham Common, and footage showed others running through the street, with some entering shops and a restaurant. Five individuals, including four police officers, were reportedly assaulted, and six teenage girls, one as young as 13, were arrested.
Businesses in Clapham expressed concern, with shopkeepers locking doors and one describing the situation as 'really scary'. Carole Powell, manager for This is Clapham, a local business improvement district, highlighted the 'weird' nature of the incident, noting that while there was damage, such as items being knocked over, a shop selling iPads reported nothing had actually been stolen. Powell attributes the behaviour to young people seeking connection, the influence of social media, boredom, a lack of resources, and a long-standing pattern of adolescents 'acting up'.
Youth advocates suggest a more nuanced understanding is needed. Jason, 17, a member of the Young People's Action Group (YPAG) advising the Mayor's violence reduction unit, described the Clapham scenes as 'chaotic, upsetting and unacceptable'. However, both Jason and fellow YPAG member Tyra, 17, believe these events highlight a critical lack of safe and structured places for young people. Tyra noted, 'Overall, young people just don't feel like they belong, so they feel the need to engage in this type of behaviour.'
This sentiment is echoed by Prince, 18, and Adnan, 18, ambassadors for the Hackney-based youth group Voyage. They explain that for most, a 'link-up' is simply an opportunity to socialise, play music, and have fun with peers, with no intention of causing trouble. Henry, 16, another Voyage ambassador, added that young people 'actually do like that human connection', dispelling the 'common misconception that young people always want to be inside, glued to their phones'.
Concerns about anti-social behaviour linked to mass gatherings are not new. In 2023, hundreds converged on Oxford Street in central London following online calls for disruption, leading to nine arrests. Southend, Essex, has also seen police use dispersal orders to manage large groups of young people gathering in the seaside town during summer months. In response to the Clapham incidents, the Mayor of London, Sir Sadiq Khan, announced in March 2026 that he would fund at least one late-night youth club for every borough, aiming to provide more positive outlets for young people.
