Police are investigating a brawl in which three people were stabbed at the 6th Annual Urban Music Awards, at London's O2 Arena on Saturday, 15 November.

Witnesses described scenes of confusion and hysteria, as up to 30 people clashed with one another, forcing Police to abandon the ceremony and seal off the venue.

Three people were treated at the scene. None of their injuries are thought to have been life-threatening.

The incident occurred at around 10pm, moments before Intensify Youth – a project aimed at combating knife crime – was about to present an award.

One guest said: “there was no security, nothing.”
