An 18-year-old man died after the car he was travelling in with three other men crashed into a ditch in Assington last night (Monday).
Police have arrested an 18-year-old man from Berkshire on suspicion of causing death by dangerous driving. He has been taken to Bury St Edmunds Police Investigation Centre for questioning.
Officers were called at around 7.55pm to reports of an overturned Red Vauxhall Corsa which had gone into a ditch along the A134.
Two ambulances, a rapid response vehicle, an air ambulance and two hazardous area response team vehicles attended the scene to treat four people.
A spokesman from the East of England Air Ambulance said: “Unfortunately, despite the best efforts of emergency services, one patient died at the scene.”
Investigating officers say the man was from Southend-on-Sea.
Suffolk Fire and Rescue sent two fire engines from Sudbury and one from Nayland.
The crews used hydraulic cutting equipment to free three casualties from the vehicle.
They were taken to West Suffolk Hospital and their injuries were not serious, according to Suffolk police.
The road remained closed until 4.45am while a collision investigation got under way.
Anyone who either witnessed the collision, or saw the red Corsa prior to it, is asked to contact the serious collision investigation team on 101, quoting reference CAD 391 of March 23.
