A police boat carrying armed officers crashed near Westminster Bridge on the River Thames, injuring five crew members. Paramedics treated victims on a black inflatable boat as police helicopters and an air ambulance circled overhead. The incident caused traffic disruption on Westminster Bridge, with nearby Underground entrances closed and a large emergency response including RNLI, Coastguard, and Port of London Authority coordinating the response. Eyewitness Mateo Bilis-Lusevic and his mother described a loud boom and officers being thrown into the water, with rescuers attending for about ten minutes. The Metropolitan Police said the incident is being reviewed to determine what happened and noted that civilians appeared unaffected so far. Authorities continue to provide updates as the investigation progresses and transit services adapt to the closure.
