Video taken inside the arena showed fans booing and shouting after the announcement while organisers said they were 'deeply disappointed by the inconvenience this has caused'.

Minaj's supporters,who go by the collective name Barbz,have slammed bosses at the 'cursed' music venue for letting them go inside and spend money despite the show not going ahead.

One fan told MailOnline that she was 'absolutely heartbroken' at the concert being called off. 'It's not exactly like the tickets were cheap,' said Alesha. 'We spent an absolute fortune to be there tonight,let alone the travel and outfits we got for it.'
