They killed 89 people in the venue, while a further 41 lost their lives in related attacks across the city. Hughes tells Sweden's TV4 that the massacre began after "the very last note of the song, almost like a diabolical syncronicity."

He says: "I knew exactly what was going on. I think I might have been the only one in the whole theatre who knew instantly. I saw a couple of girls go down and then we were able to get off the stage. I didn't see my girl, Tuesday, and I went to the backstage area. When I opened up a hallway there was a dude at the end of it, holding a gun.

"He didn't see me. The door shut behind me and I was trying to back up, like very very sneaky. But he noticed me. I thought I was dead - I waited for the shots to hit me."

But as the terrorist pulled his rifle from his back, the barrel struck the doorframe above his head, giving Hughes time to escape. "I opened the door and he started firing and his rounds shot the door behind me," he remembers.
