A MASS brawl involving up to 50 people began after a professional boxer mouthed a provoking comment to his opponent.

The boxing match between Luther Clay and O'Shane Clark at Bracknell Leisure Centre on March 17, led to a group of spectators starting a fight.

Around 50 people were involved in the fight, with at least 11 men aged between 21 and 49 injured.

Some of the victims required hospital treatment for their injures.

The offenders are described as a group of both white and black men aged in their late teens and fifties.

Thames Valley Police also confirm that some people were using bladed weapons, but no knives have been located at the scene.

A small black car was also reported to have sped off from the scene when emergency services arrived.

Police cordoned off the sports centre that night and a forensics team were investigating inside the building the following day.

Investigating officer PC James Doel, of Force CID based at Maidenhead police station, said: “This was a large scale affray with a number of people injured.

“I am appealing to anybody who witnessed what happened and knows the identity of any of the offenders to contact police with what they know.

“I am also asking anybody who was present and may have recorded the incident on a mobile phone to make contact.

“Similarly, if anybody else was injured, and have not yet contacted us, please do so."

Amateur boxer Luther Clay spoke in an interview to Grassroots Boxin after the match, which said: "I am sorry about tonight, I completely messed up.

"There was a fight because of my mouth.

"To Shane and his team, I am sorry for my behaviour."
