And things got out of hand after the crowd witnessed their countryman Kamobosos lose his world titles.

There were several instances of fighting on the streets surrounding the venue and sad scenes as more than one man was knocked out cold.

One fan filmed the injuries he sustained including a black eye and cuts to his face – another was pushed to the ground and attacked by a group of around five young men.

Meanwhile, inside the arena Haney entered the record books by coming the eighth boxer in history to win each of the four world title belts.

Prior to the fight the American held the IBF lightweight belt but beat Kamosos to collect the WBA, IBF, WBO and lineal crowns.

That means he has unified the lightweight division at the age of just 23 – becoming the first person to achieve the feat since Pernell Whitaker in 1990.

After the fight Haney said: “This is a dream come true.

“I was comfortable. I was sticking to the game plan, the game plan was to go in and hit and not get hit and I did that for the majority of the fight.
