Teen mobs threaten violence amid 36C heatwave: Fears over half term 'linkup' in Southend after chaos erupted in Brighton, Hackney and Clapham over bank holiday weekend

Published: 10:04, 26 May 2026 | Updated: 10:28, 26 May 2026 Teen mobs have planned another wave of violent 'linkups' across the country amid the 36C half term heatwave. The hottest Bank Holiday on record yesterday saw chaos unfold in Hackney where someone was allegedly shot at an unofficial 'day party', while panic unfolded in Brighton after a stabbing. Elsewhere, youngsters flocked to Clapham again on Sunday where a 17-year-old boy was stabbed during another 'linkup'. Footage posted online show police in attendance and one officer chasing someone. Fights also broke out on Seaham beach in Durham and in Southend, Essex, yesterday where police were filmed arresting a teenager. Yesterday, the UK experienced its hottest Bank Holiday of all time after a searing 34.8C was recorded in Kew Gardens, south-west London. The mercury is set to rise even further today to an unprecedented 36C, which will undoubtedly see people flock to beaches and commons to enjoy the heatwave. But posts on social media revealing plans for the mobs to return to Southend today could make anyone heading to the Essex seaside town second-think. Images appear to show multiple boys posing with zombie knives and machetes as they urge others to attend. One picture appearing to show a young man holding a knife and asking who is going to Southend on Tuesday seems to show a poster advertising the unofficial event A social media user took to TikTok to warn his peers not to attend, telling them: 'As some of you may be aware, there was a shooting today at Hackney motives. 'I wanna say, be safe, do the right thing, but tomorrow, if you wake up and purposely decide to go to Southend, you deserve whatever is going to come to you, bruvva. 'Southend tomorrow, just think to yourself, is that a good idea? Posts on social media have revealed plans for the mobs to return to Southend today On Seaham beach, families with children watched on as a large crowd formed around an apparent fight that broke out in the scorching heat Videos posted online showed a huge crowd gathered in Brighton after the incident with people heard crying and wailing while police tape can be seen cordoning off the area as officers walked around the scene 'It seems to me like, as the weather gets warmer, people don't know how to act, people lose their heads, people don't want to have fun - people just want to kill people. 'So whatever you're doing tomorrow, be safe and go to Southend at your own risk.' Southend has become a hotspot for teen troublemakers in the summer. Last year, ten teenagers admitted a range of offences including violent disorder and conspiracy to cause grievous bodily harm after yobs descended on the seaside town with machetes and chased each other through the streets. In 2024, families watched on as the violent disorder erupted by the beach and High Street in Southend-on-Sea in July. It followed an invite to bring alcohol, drugs and nitrous oxide to a 'beach rave' on what had been the hottest day of the year. The footage from yesterday showing people gathered around as a young boy was arrested included a caption saying: 'Guys really wanna talk about going to Southend on Tuesday as if today wasn't bad enough.' People then posted images in the comment section which seem to show young men brandishing large knives and wearing balaclavas with menacing captions, such as: 'Who's stepping Southend tomorrow?' Some youngsters replied with claims the pictures had made them change their mind about attending today's meet up. Clapham has also become a popular 'linkup' location in London this year after children from rival high schools planned to meet there over Snapchat. The disorder in March saw 100 officers called to Clapham High Street where groups of teenagers were rushing into shops and allegedly stealing. Six arrests were made over the course of two days of madness in the area after five people were assaulted - four of which were officers. Police are appealing for witnesses after a teenager was stabbed outside Shelter Hall in Brighton. It followed reports of a large group of people fighting in the area around 9.25pm on Monday, May 25. The victim, a boy from Surrey, was taken to hospital for treatment, where his injuries were confirmed to be superficial.
