AN AMATEUR martial arts fighter has died after suffering a brain injury in a match on Saturday night.

The woman, named on the "Fast And Furious Fight Series" event's Facebook page as Sai Aletaha, 26, collapsed at the Central Hall venue in Southampton.

She was taken to hospital in a life-threatening condition but died the following day.

Police say they were not treating the death as suspicious.

A spokesperson for Hampshire Constabulary said: "We were called shortly before 1am on Sunday 17 November by colleagues at Southampton General Hospital informing us of a woman who was being treated in hospital for a life threatening brain injury.

"The woman, aged 26, died in hospital later that day.

"The death is not being treated as suspicious and we are preparing a file for the coroner.

"Next of kin have been informed."

Meanwhile, tributes to Ms Aletaha were posted online.

A post on Southampton's Lookborai gym's Facebook page said: "Following the show Saturday we regret to announce that one of our team mates unfortunately suffered an injury leaving her in a critical condition that she tragically will not recover from.

"Saeideh Aletaha was a lovely character with a beautiful soul. Her dedication to the sport was 110% travelling miles every day just to train.

"She found her place with us just a few months ago but has become a part of the family and will be sorely missed.

"This news comes as a devastating blow to us all at the gym and the whole community. Our thoughts and [prayers] go out to her family."

A South Central Ambulance Service spokesman said an ambulance was sent to Central Hall to answer a call shortly after 8.50pm on Saturday reporting that a participant in a martial arts event had collapsed.

A statement from Hampshire Police said: "We were called shortly before 1am on Sunday November 17 by colleagues at Southampton General Hospital informing us of a woman who was being treated in hospital for a life-threatening brain injury.

"The woman, aged 26, died in hospital later that day.

"Inquiries into exactly what happened are ongoing. Next of kin have been informed."

A post on the event's Facebook page said: "All competitors get in prepared that they may be injured and this is something not expected to happen 99.9% of the time.

"But, it can and in this we make the environment as safe as possible with pre and post medicals from a doctor, and full medical cover throughout with doctor, paramedic and ambulance on site alongside our experienced team of staff with numerous first aiders, safety is not something ever skimped on in any of our 19 shows and all matches are made equal.
