Four people – including a 14-year-old boy – all remain in a serious condition in hospital following a crash on the Stevenage A602 last week.

A green Vauxhall Astra collided with a black Ford Fiesta and a white and blue arctic lorry on Broadhall Way – at the roundabout for Shephall Way – at about 4pm on Wednesday, December 16.

The Astra driver – a 78-year-old woman – remains at Lister Hospital in a serious condition, as does her 83-year-old male passenger.

The 39-year-old woman driving the Fiesta is also still at Lister in a serious condition, while two 14-year-old boys in the car were taken to Addenbrooke’s Hospital in Cambridge. One sustained slight injuries and has been discharged, but the other boy remains there in a serious condition.

The driver of the lorry suffered shock but did not require hospital treatment.

The road was closed for four hours while an investigation was carried out and PC Alison Elderfield from the Bedfordshire, Cambridgeshire and Hertfordshire Road Policing Unit is urging anyone with information to come forward.

She said: “The collision occurred at a time when there were a number of other motorists travelling along the road and we’d like to speak with anyone who witnessed what happened.

“We’d also like to speak with anyone who saw the vehicles in the moments prior to the incident. If you have any information please contact me or Sergeant Karl McDermott via the non-emergency number 101, quoting Operation Dander.”
