Investigations are continuing into last week’s double fatal M11 crash which killed a brother and sister and seriously injured another two motorists.
The incident happened on the northbound carriageway near junction 8 for Stansted Airport at 2.15pm, and involved a lorry, two cars, a van and a horsebox belonging to Wiltshere racing trainer Brian Meehan.
An Essex Police spokeswoman said: “The two people who died are believed to be a 53-year-old man from the Netherlands and a 45-year-old woman from Kent, who were brother and sister. Their family has been informed.
“They were in a Toyota car that was struck by other vehicles and collided with the rear of a Mercedes horse box, with five horses on board.
“The car caught fire on impact and sadly the occupants died at the scene.”
Meanwhile, the 49-year-old driver of a Jaguar car from Romford received head injuries and was taken by ambulance to Addenbrooke’s, and his passenger, a 23-year-old woman from Cyprus, who was due to catch a flight from Stansted Airport, was flown by air ambulance to the Cambridge Hospital with serious injuries.
The drivers of a lorry, the horsebox and a Vauxhall van received minor injuries.
The lorry driver – a 49-year-old man from Stafford, Staffordshire, was arrested on suspicion of causing death by dangerous driving. He was questioned and later released on police bail until September 15.
