Five people were injured in a stabbing on a busy west London street following a violent brawl in Acton on Friday afternoon, police said.According to the Metropolitan Police, officers patrolling Horn Lane were alerted at around 2.47pm to reports of a number of people being attacked and stabbed. All five victims were given emergency first aid at the scene before being taken to hospital.Four of the injured, aged 20, 22, 42 and 47, suffered stab wounds, although police said their injuries were not considered life-threatening or life-changing. A fifth man, aged 26, was also taken to hospital, where he was later arrested on suspicion of grievous bodily harm (GBH) and possession with intent to supply Class A and B drugs.Police confirmed that the suspect is still under medical care while the investigation continues.The London Ambulance Service said multiple emergency teams, including advanced paramedics and tactical response units, were deployed to the scene after receiving a distress call shortly before 2.50pm.Chief Superintendent Jill Horsfall said the incident would naturally cause concern to residents and assured the public that detectives were working to establish the full sequence of events.“We recognize this will be worrying for the local community and want to reassure them that our detectives are working quickly to establish exactly what happened,” he said.Police said there would be an increased security presence in the area over the coming days and any witnesses or anyone with information was urged to contact officers.Pictures circulated on local community forums reportedly showed several injured people being treated outside a nearby electrical goods store.The incident comes amid ongoing concerns over knife crime in England and Wales, although recent figures show a decline in knife-related crime and murders in 2025 compared to the previous year.
