Two motorists have been arrested on suspicion of causing death by dangerous driving after a motorway collision in the early hours of the morning. A man in his 20s was pronounced dead at the scene on Saturday morning after a crash involving a silver Vauxhall Vectra and a grey BMW 1 Series. He was a passenger in the Vectra when it crashed into barriers near junction 4 on the M11 in Redbridge, east London. Three other men, including the driver, needed hospital treatment, the Metropolitan police said. Officers were called at about 12.50am, police said. The family of the dead man have been informed. A 22-year-old woman driving the BMW was arrested on suspicion of causing death by dangerous driving and taken into custody. The driver of the Vectra, a 24-year-old man, was arrested on suspicion of causing death by dangerous driving and driving while disqualified. One man travelling in the Vectra remained in critical condition on Saturday, while the conditions of the driver and another male passenger were not thought to be life-threatening. Police have appealed for any witnesses, or anyone with dashcam footage of the collision or the moments beforehand, to call them on 101.
