A van driver who failed a roadside drugs test has been arrested on suspicion of causing death by dangerous driving after a man and woman died in a Fenland collision.

The head-on collision involved a car and a van and took place on the A142 Isle of Ely Way, Chatteris, last night (Thursday September 3) just after 8pm.

Emergency services attended but the driver and one of the rear passengers of the Ford Focus, both in their 30s, died at the scene.

Two children were also in the car. They suffered minor injuries and were taken to hospital, where they remain this morning.

The driver of the van suffered minor injuries. The 32-year-old man from Lincoln failed a roadside drugs wipe and was subsequently arrested on suspicion of two counts of causing death by dangerous driving, and driving whilst unfit through drink or drugs.

He remains in custody at Thorpe Wood Police Station.
