Joe Gregory was sitting in his car outside the venue when the device was detonated by a suicide bomber shortly after 10.30pm, killing at least 22 people and injuring 59.

The arena lights up before a loud bang rings out and seconds later the 22-year-old can be heard shouting: “No!” Mr Gregory, who posted the footage on Twitter, was waiting to collect his girlfriend and sister who were at the concert. He later informed followers that both were “home safe and well”.
