Police have swarmed Westminster Bridge after a man was attacked in front of horrified tourists just metres from the Houses of Parliament.
Initial reports suggested he had been stabbed. but the Metropolitan Police later said he suffered a cardiac arrest after a fight.
Officers were called to Westminster Bridge at around 10.45am today and found the man who was said to be ‘fighting for his life’ after being taken to hospital in a critical condition, according to Scotland Yard.
A user of X, formerly Twitter, posted online: ‘Westminster Bridge closed in both directions. Hundreds of Police at the scene with the Bridge cordoned off. What’s going on?’
Horrified passers-by looked on as dozens of police officers and emergency services workers were called to the scene, with the busy bridge closed in both directions.
Three people have been arrested on suspicion of attempted murder and one other for affray.
Two of those arrested have been treated in hospital for minor facial injuries, the Met said.
Scotland Yard said they were not treating the incident as terror-related.
A road closure was put in place and the 11, 12, 148, 159 and 453 bus services were all being diverted.
