Live music venue Roxx was evacuated this evening following reports that the ground floor ceiling had collapsed.
The venue which is above Aura, just off Bedford Place, was hosting a gig by The Story So Far when the accident happened.
Alex Brown, a Southampton student who was at the gig told The Edge that the sound stopped halfway through the second song of the set, and security guards triggered the fire alarm and asked the audience to leave.
“The security guard said he was really sorry but it was not safe, we all had to leave.”
The extent of the damage is not yet clear, and information about whether future gigs will go ahead has not been provided. Wheatus are due to play the venue next Monday.
The venue – which opened in November 2012 – has previously played host to acts including Disclosure and Mr Scruff.
The band have now rescheduled the gig, and will instead be performing at 11.30pm this evening at Unit.
