Mercury CEO Lucian Grainge says: "At this point, we have confirmed that Thomas Ayad, an international product manager for Mercury, lost his life in the attack on the theatre."

The crew member Nick Alexander, 36 and from Colchester, was working on the band's merchandise desk when gunmen burst into the Bataclan venue and opened fire before detonating suicide bombs.

More than 80 people are believed to have died at the club, while in total 129 were murdered across the French capital in a series of coordinated attacks. Extremist group IS have claimed responsibility.

In a statement, Alexander's family say: "It is with huge sorrow that we can confirm that our beloved Nick lost his life at the Bataclan last night. Nick was not just our brother, son and uncle. He was everyone's best friend - generous, funny and fiercely loyal.
