Three men suffered stab wounds in London last night during a mass brawl at the Urban Music Awards.
A man has been arrested after one guest was seriously hurt and two others suffered minor injuries.
The trouble, which began shortly after 10pm, forced organisers the cancel the ceremony at the O2 Arena after an hour-and-a-half.
One Eyewitnesss spoke of seeing "blood all over the floor" while another told Sky News that guns had been seen in the auditorium.
The 300 guests who attended the ceremony were held at the Indigo2 – a smaller capacity club inside the arena – before being questioned by police.
Leona Lewis, Adele and Lethal Bizzle were among the artists nominated for awards. At present, it’s not clear whether they were in attendance.
The incident forms part of another weekend of violence across the UK involving knives after two men died of stab wounds in separate incidents in Greater Manchester.
