Watch: Hip-hop entourage in violent Auckland CBD brawl

In case you missed it: This was one of the Herald's top stories on social media this week.

Video footage has emerged of the aftermath of a violent brawl involving American hip-hop duo Rae Sremmurd and their entourage in downtown Auckland.

A member of the duo was left with blood on his body following the confrontation outside SkyCity in Auckland's CBD.

Emergency services were quick to arrive at the incident where a man was injured by a broken bottle shortly after 4pm at the intersection of Victoria St West and Federal St. While it's unclear what role the American duo and their entourage had in the incident, member Slim Jxmmi was seen talking to police with blood on his forearm and torso soon after.

Slim Jxmmi also posted a live video on Instagram showing a bandaged hand, along with footage of the Sky Tower.

Jxmmi and his brother Swae Lee, who have released three albums and are best known for their single "Black Beatles" are performing at the Logan Campbell Centre in Epsom on Friday night.

American hip-hop act Rae Sremmurd were involved in the altercation in the CBD that saw one man taken to hospital yesterday.

A witness told the Herald he heard a scuffle and a bottle shattering at about 4pm. When he looked over he saw seven men fighting and the broken bottle being used as a weapon.

Another witness said the American group were walking down the street when someone called out to them, sparking a verbal confrontation. The American group appeared to be walking away when they were attacked by a member of the other group, the witness said.

One man who contacted the Herald saying he was involved said he challenged the Americans because they were filming a friend of his - a homeless man who had been drinking.

He thought it was inappropriate and in turn decided to film the group himself but they took offence to being filmed and confronted him.

He said words were exchanged between the two parties before a fight ensued.

Following the incident, one man was transported to Auckland Emergency Hospital with serious injuries, St John spokeswoman Chrissy Hamilton said. It is not clear if that person was a member of Rae Sremmurd.

The scene in Federal St.

A senior sergeant told the Herald at the scene no one had been apprehended by police but there were a number of suspects they were chasing.

Blood spatters could be seen on the footpath of Federal St with a trail of blood-spots leading towards Victoria St West.

Police officers investigating the incident were scanning the ground for evidence, filling brown evidence bags as they moved along.

SkyCity staff were seen speaking with police officers but would not comment when approached by the Herald.

The Herald is trying to reach Rae Sremmurd for comment.
