A van driver from Lincoln who crashed head-on into a car, resulting in the death of a man and woman, has been arrested.
The 31-year-old man was driving on the A142 Isle of Ely Way, Chatteris in Cambridgeshire at around 8pm on Thursday.
He crashed into a Ford Focus which had four people inside.
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 for treatment.
The van driver suffered minor injuries but was arrested after failing a roadside drugs wipe, Cambridgeshire Police said.
He was arrested on suspicion of two counts of causing death by dangerous driving, and driving whilst unfit through drink or drugs.
The man remains in custody at Thorpe Wood Police Station while investigations continue.
