Officers were called out to the crash – described by eye-witnesses as ‘like an explosion’ – just before 3am today – four men, aged 18, 19 ,19 and 21, were pronounced dead at the scene.
A local journalist covering the collision on the Leeds Outer Ring Road of the A6210 near Horsforth said a firefighter called to the carnage arrived to find his daughter among the injured victims.
The crash involved a grey Seat Leon car and an Uber taxi which was a grey Seat Alhambra people carrier.
Emergency services have so far not confirmed the reports.
Witnesses say they saw a woman crawl from the wreckage as a local doctor tried CPR on two people who were dragged from the vehicle.
The accident happened directly outside the home of Steph Callaghan, 31, who said she went outside and saw the scene unfold before her.
She said: “I was awake, getting myself a drink, when I heard a speeding car. It was that loud that I thought it was a motorbike.
“Then there was a screech of tyres and a big explosion of noise. The crash was so bad you could not make out how many cars were involved. It was just a mess of metal.
“I came outside and heard a man on the phone calling for an ambulance, and saying ‘there is blood everywhere’.
“I saw a young female crawl out of the wreckage. The taxi driver looked surprisingly alright.”
Ms Callaghan said about 20 minutes after the crash a distressed woman turned up screaming “where is she, where is she?”.
Plasterer Allan Vickers, 39, said: “It was absolute chaos and carnage. The two cars were totally destroyed. A doctor neighbour of mine came out of his house and tried CPR on two people who were dragged out of the car, but they were beyond hope.
“I was told not to go near the car because there were bodies still in there.”
The occupants of the Leon car were all known locally and it was reported on social media that they were at a house party earlier that night.
A 16-year-old and 17-year-old girl survived the crash.
The 16-year-old girl remains in critical condition and and the 17-year-old’s injuries are considered non-life threatening.
The driver of the Alhambra is a 42-year-old man from Bradford and was taken to the hospital with serious injuries, but they are not considered life threatening.
Flowers have been laid at the crash site on Broadway as police continue to appeal for witnesses.
