Manchester attack: Chilling footage captures moment concert-goers descend into panic after huge explosion

Horrifying footage has captured the moment thousands of teenage fans descend into panic after hearing a huge explosion at the Manchester Arena.

At least 22 people were killed and 59 injured in Monday night's terrorist attack, which is feared to have been carried out by a suicide bomber.

The blast went off as crowds departed the arena at 10.30pm following a concert by US pop star Ariana Grande.

Footage has emerged of the moment fans still inside the arena heard a harrowing ‘boom’ reverberate around the venue.

The chilling clip shows thousands suddenly begin screaming in fear and clambering over seats in scenes of total confusion.

Two girls can be heard saying: “Oh my god. What’s going on? What just happened?”

As they realise the seriousness of the situation they grow scared and the footage ends with a chorus of screaming and fans running panicked.

A huge police presence quickly arrived on the scene as hordes of fans, including thousands of teenagers, poured out of the arena.

Police confirmed this morning the attacker, who was acting alone, killed his victims using an improvised explosive device. He died at the scene.

The wounded were showered with glass and metal nuts after a "huge bomb-like bang" went off at as people waited to leave the arena after the show finished.

They were taken to six hospitals around Manchester. Sixty ambulances were called to treat people at the arena.

Concert-goers today told of their terror after the explosion.

Abby Mullen described how she was metres away from the explosion and was left covered in blood of victims after the blast.

She said: "As we were leaving a bomb went off metres in front of me.

"That sound, the blood & those who where running around clueless with body parts & bits of skin missing will not be leaving my mind any time soon or the minds of those involved."

Gary Walker, from Leeds, was with his wife in the foyer waiting to pick up his two daughters who were at the concert.

"I was waiting for the kids to come out. We heard the last song, and quite a few people were flooding out and then suddenly there was a massive flash and then a bang, smoke," he told BBC Radio 5 Live.

"I felt a bit of pain in my foot and my leg. My wife said, 'I need to lie down'. I lay her down, she'd got a stomach wound and possibly a broken leg.

"I was about three metres from the actual explosion. I am surprised I got away so lightly."

Mr Walker said the explosion was by the door in the foyer, next to the merchandise, and that glass and metal nuts were left on the floor. He said he lay down next to his wife for up to an hour, until she was stretchered on a table to an ambulance.

His daughter Abigail, who was still in the auditorium with sister Sophie at the time of the explosion, said: "I had to make sure I had my sister. I grabbed hold of her and pulled hard. Everyone was running and crying.

"We were just trying to figure where everyone was. It was absolutely terrifying."

One fan, Majid Khan, 22, described the explosion and ensuing panic.

"A huge bomb-like bang went off that hugely panicked everyone and we were all trying to flee the arena," he said.

"It was one bang and essentially everyone from the other side of the arena where the bang was heard from suddenly came running towards us as they were trying to exit."

Oliver Jones, 17, who attended with his 19-year-old sister, said: "The bang echoed around the foyer of the arena and people started to run.

"I seen people running and screaming towards one direction and then many were turning around to run back the other way."

All national general election campaigning has been suspended in the wake of the attack.

Theresa May said her thoughts were with the victims and families of those affected in the Manchester incident, which is being treated as an "appalling terrorist attack".

The Prime Minister said the authorities were working to establish what happened at the Manchester Arena, after 19 people were confirmed dead following reports of an explosion at an Ariana Grande concert.

Mrs May said: "We are working to establish the full details of what is being treated by the police as an appalling terrorist attack.

"All our thoughts are with the victims and the families of those who have been affected."

Jeremy Corbyn said: "Terrible incident in Manchester. My thoughts are with all those affected and our brilliant emergency services."

Tim Farron added: "This is a shocking and horrific attack targeting children and young people who were simply enjoying a concert.
