Panic and chaos gripped passengers on a London-bound train on Saturday evening after a mass stabbing left ten people hospitalised, nine with life-threatening injuries. Witnesses described scenes of terror as a man armed with a large knife moved through the carriages, sending passengers fleeing for their lives.One passenger told Sky News he saw a man “extremely bloodied” stumble through the carriage shouting, “They’ve got a knife, I’ve been stabbed.” He said, “That person ended up collapsing on the floor. They were taken to an ambulance pretty much straight away.” Others recalled people sprinting through the train to escape as the attacker moved through carriages.Wren Chambers, who was also on board, told the BBC they ran to the front of the train after seeing a man bolt past with a bloody arm, shouting “they’ve got a knife, run.” “We were pretty scared once we knew what was happening,” Chambers said. “We were able to get off the train unharmed.”When the train came to an emergency stop in Huntingdon, Cambridgeshire, armed officers stormed the station. A witness described seeing police “directing their weapons at a man on the platform with a large blade.” The suspect was eventually “tasered and restrained,” said another passenger, Gavin. “He then was waving a knife, quite a large knife, and then they detained him. I think it was a Taser that got him down in the end,” he told Sky News.Passengers described “blood everywhere” and people hiding in toilets as the attack unfolded. One told The Times that others were getting “stamped on” in the rush to escape. Another described the horror as “like something from a film — really violent.”British Transport Police confirmed ten people were taken to hospital, nine with “life-threatening injuries.” Counter-terrorism officers are assisting with the investigation, though the motive remains unclear. The national “Plato” emergency response protocol used for potential terror attacks was activated.Prime Minister Keir Starmer called the incident “appalling” and “deeply concerning,” praising emergency services for their swift action. “My thoughts are with all those affected,” he said.Police arrested two suspects at the scene and continue to examine the train, which remains cordoned off as a major crime scene. The East of England Ambulance Service said it deployed a “large-scale response,” including air ambulances and tactical teams.Cambridgeshire mayor Paul Bristow said he was aware of “horrendous scenes,” adding that his “thoughts and prayers” were with those injured.
