A witness to a major incident in Birmingham in which multiple people were stabbed said the fight she saw on the same night looked "targeted" and "racial".
Cara Curran, who works as a club promoter, said she sees many fights, usually over "girls" or when someone's drink is taken, but last night's violence was different.
West Midlands Police declared a major incident and said that one man has died and seven people have been injured.
Explaining what she saw, Cara told BBC Radio 5: "The fights that happen are just because they’ve had too much to drink and it’s over petty things like girls or, you know, someone takes someone’s drink.
"This seemed more like it was one group of boys against another group of boys and it seems quite targeted."
Cara explained the "language they were using" made her think it was a serious fight that may have been planned in advance.
She said: "These people, their body language from leaving the club was like they were prepared for something, they were not just having an argument and then fighting, it was straight into fists being thrown, there was not much talking going on."
Cara said the security tried to pull the fighters off each other but "they would just keep going at it", even though she reckoned there were "at least" 10 bouncers trying to break it up.
The club promoter said during the scrap she saw jewellery flying everywhere and clothes being ripped – with one lad ending up with a bald spot after his hair was ripped out.
Noting she didn't hear any mention of what started the fight, Cara added: "This time it was just slurs being thrown about, racial slurs.
"Most of it was racial slurs, with one of the clubs I work at it is mainly populated by black culture, Asian culture, so for racial slurs to be thrown around it was quite rare."
In a statement this morning, West Midlands Police said: "We can confirm that at approximately 12:30 am today we were called to reports of a stabbing in Birmingham city centre.
"We immediately attended, along with colleagues from the ambulance service.
"A number of other stabbings were reported in the area shortly after."
Chief Superintendent Steve Graham there is no suggestion stabbings in Birmingham were "motivated by hate".
He said police are looking for one suspect.
