Six people were injured when violence broke out at the official Mobo Awards aftershow party in Liverpool.
Merseyside Police were forced to shut down the event at the Hilton hotel in the early hours of Thursday after a number of gatecrashers gained entry.
A disturbance broke out and emergency services were called by worried revellers just after midnight.
Six men were treated for head, face and eye injuries. However, no complaints of assault were made to police.
A Merseyside Police spokeswoman said: "The party in Hilton Hotel following the Mobo Awards became overcrowded and there was a disturbance.
"We utilised our licensing powers to close the bars in the hotel at about 1am."
Among those treated by paramedics was a 30-year-old man who was knocked unconscious and a 20-year-old who was glassed in the head.
They were taken to Royal Liverpool Hospital, along with another man, aged, 30, who had fallen.
Three other men who suffered glass and facial injuries refused to go to hospital, the North West Ambulance Service (NWAS) said.
Officers are now expected to speak to hotel staff and the event organisers to establish whether they received any complaints.
Earlier, pop heart-throbs JLS and hip-hop MC Tinie Tempah shared the major spoils at the Mobo ceremony, winning two prizes each.
There was also a prize for former rap battle champion Professor Green, who was named best UK hip-hop and grime act.
The awards, which stand for Music of Black Origin, were first handed out in 1996 to showcase British urban music at a time when it was largely overlooked in the mainstream.
