“The venue was aware of a group of 20 girls who had tried to start on lots of different individuals throughout the night.

“Two of these girls then started on me. My daughter was jumped, then the other half jumped myself.

“We were both kicked, punched and stamped on. We got separated when I left the venue looking for my daughter and she was inside receiving medical treatment.

“I was outside looking for my daughter when I was surrounded by these girls. It kicked off a few times and they were fighting with other groups of girls outside.

“I was then bit by a girl and the security moved me in front of him, where I was then bit by the private security’s dog out of nowhere.

“I'm now in A&E waiting for a tetanus and blood tests. My phone was also stolen by these girls.”

Ms Leigh-Jackson said police attended the scene at around 11.20pm and took statements from herself and her daughter.

Another concert attendee Emma Kirkum said: “We have all visited various venues across the country, including the BIC and have never experienced or witnessed anything as we did on Monday.

“There were three incidents whilst the band were performing, which resulted in the show stopping."

She said there were two fights during the event and a reveller also needed medical assistance.

She added: “The atmosphere within the venue felt toxic and charged."

A Dorset Police spokesperson said: “Dorset Police received a report at 8.07pm on Monday, November 14, of an assault at the Bournemouth International Centre in Exeter Road.

"Officers attended, however no victim was identified.

“At around 10.45pm officers were called to assist with a large crowd leaving the Bournemouth International Centre in Exeter Road.”
