Police investigating a fatal collision on the A47 near Wisbech which claimed the lives of two young girls are appealing for help to trace the driver of a red car.
The incident happened on Thursday 27 December 2012 at approximately 6.40pm at Walsoken when a black Ford Focus left the road and overturned, coming to rest on its side at the edge of a ditch.
It happened about 500 metres north of the Broad End Road junction as the vehicle travelled towards Wisbech.
Tragically, sisters Tamzin and Jessica Portor, aged 10 and seven and from Sutton Bridge in Spalding, died as a result of injuries sustained in the collision.
Three other people travelling in the car, a 12-year-old boy, 38-year-old man and a 43-year-old woman, all suffered minor injuries.
Officers from Norfolk Constabulary's Serious Collision Investigation Team (SCIT) are keen to speak with the driver of a red car seen travelling towards King's Lynn around the time of the incident.
