The force have this afternoon (September 22) appealed for information and dash cam footage following the smash involving a blue Ford Fiesta and a white Vauxhall Corsa at 7.15pm last night. A spokesperson said officers attended alongside the East of England Ambulance Service and that a 33-year-old woman and a 19-year-old man were taken to hospital. The crash near junction 21 caused two lanes to close southbound for several hours, with one reopening at 1am and the other shortly before 3am. In a social media post at the time, police warned drivers to avoid the area as the crash was causing delays. Anonymous reports can be made via Crimestoppers.
