S Club fans were left furious after they were forced to evacuate their much-loved gig at Liverpool's M&S Bank Arena on Monday.
A fire alarm siren was triggered again leaving the arena in complete darkness at 9pm, while the band were performing their song Alive.
Earlier this month, the group were forced to cancel their scheduled gig again because of another suspected fire.
The band - Tina Barrett, Jon Lee, Bradley McIntosh, Jo O'Meara, and Rachel Stevens left fans devastated when their concert got cut short.
