Shocking video shows the aftermath of a fatal crash which left four people dead.

Muhammad Danyaal, 19, Farhan Patel and Mohammed Jibrael Mukhtar, both aged 18, and taxi driver Masrob Ali, 54, all died after two vehicles crashed in Bolton in the early hours of Sunday morning.

The three teenagers were inside a ‘souped up' red Seat Leon, according to reports, when it collided with a Citroen C4 Picasso, which was being driven by Uber driver Masrob, at around 12.45am.

The video shows the smashes up cars and emergency workers, seven minutes after the crash.

The driver was caught on camera hitting speeds of 120mph in a residential area, at 3Ppm on Saturday, and Greater Manchester are reviewing this as part of an investigation into the crash, a BBC report said.

Five passengers, from both vehicles, were still in hospital yesterday, including one 29-year-old woman with life-threatening injuries, reports said.

A source, who does not want to be named, came upon the scene moments after the incident and took the video.

They said: "This was so upsetting to see. It took me a while just to take it in - I was in shock."

"It's been such a terrible shock to Bolton's community."

"All my thoughts are with the families."

"I saw a line of blue lights and thought someone was being pulled over."

"Then I saw loads of fire engines and ambulances, and even more ambulances arriving, and a massive police presence."

"I thought, ‘this is not normal'."

The onlooker was redirected by police.

They said: "We need to invest more in educating young people about driving safely. I can't think why a young person would be driving a powerful car like that."

"Their brains aren't fully developed yet, They shouldn't have other young people, unqualified, or even newly qualified drivers in the car for a while after taking their test."
