Police in Northamptonshire are appealing for witnesses after a woman was killed in a motorcycle crash.
The 29-year-old from Leicestershire died after the accident between junctions 16 and 17 of the M1 northbound. It happened at just before 11pm on Sunday night.
The woman had been riding a white Yamaha R6. Officers would like to speak to anyone who might have information on the accident, and specifically anyone who saw two other motorbikes - a multi-coloured Yamaha R1 and a grey Nissan GT-R - travelling northbound on the M1 at the time.
