Police are looking to trace a number of drivers who would have seen an incident involving a speeding car on the M11 on the evening of Thursday July 23.
A silver Honda Jazz was seen driving at speed and undertaking two cars on the southbound track between the Theydon Interchange and Loughton Interchange (junctions 6 to 5) at 11.25pm.
The car was stopped by a police officer and the driver, a man aged in his 40s from London, was reported for careless driving and speeding.
Officers wish to speak to the drivers of the other two cars and any others who saw the Honda Jazz travelling in the area at the time, as they may have further information to help with police enquiries.
They would also like to speak to anyone with dash cam footage.
