RITA Ora’s album launch party at a nightclub was derailed by a terrifying security scare with an out-of-control fan.
The superstar’s appearance on stage at the the intimate gig was delayed by an hour after the tracksuit-wearing man began behaving erratically among the crowd
Security staff intervened to try to calm down the unnamed fan, but they were forced to call police to deal with him.
A source said: “Whatever his motivation, it caused a huge scene – it’s very scary when someone seems totally uncontrollable in a crowd.
“They were already inside the venue but nobody was quite sure what he wanted to achieve – as soon as he started behaving suspiciously the police piled in.”
