A student has died after she was reportedly crushed under a fence which was pushed over outside a Durham nightclub.
A 20-year-old student has died in a reported crushing incident in a nightclub queue in Durham.
It is thought that the first-year student had become trapped when a queue to get into the popular Missoula club on Wednesday night got out of control.
A resuscitation attempt was made by a doorman, but to no avail.
A rival students' union night held at the same time had also recently stopped running, he said, meaning Missoula was probably busier because it was the only big club operating.
The rear entrance was reserved for members of student sports clubs and the front used by everyone else, he said.
It is understood Miss Burt had been on an evening out with the Durham University Sailing Club.
Olivia Burt was described as an "exceptional sportswoman" and an "outstandingly able student".
Miss Burt, from Hampshire, was a former head girl at Bournemouth School for Girls (BSG) and was an accomplished sailor, having been part of the British Sailing team in the European Championships.
'Olivia sailed for more than a decade, quickly finding her place in the university team.
'Those students close to her have lost a wonderful friend, whom in their shock they grieve for, alongside her family and friends.
In a number of heartbreaking tributes posted on social media, friends describe the student as "a bright, handsome and kind person".
Chris Atherton, its senior high performance manager, said: "The RYA is deeply saddened to learn of this tragic incident".
"My thoughts go out to her family at this tragic time".
Tributes came in on social media for Miss Burt.
"The girl was stuck under it and people just piled up on top of her".
Eyewitnesses say the woman, 19, became trapped under the barrier which toppled over outside the Missoula nightclub in the city's Walkergate last night.
He said: "There was a fair bit of panic".
Onlookers claimed a security man was seen ripping off his shirt to use as a cloth to stop the bleeding from the woman's head. I got pushed from my right shoulder towards my left, towards my mate who was by the barrier.
Another student, named only as Jack, said he had queued for an hour before deciding to leave at about 11.15pm. People were trying to reason with them, telling the bouncers it wasn't safe and someone was going to get hurt. My friend was pulling people off her but there were too many.
Police, who were called to the scene at 11.53pm last night, have launched an investigation into circumstances leading up to her death.
A post-mortem examination has been carried out.
Eyewitness reports recount overcrowding and a sense of panic outside the venue.
Missoula reopened in September 2016 after a £385,000 investment.
In a statement, Missoula said it was "a awful accident" and said staff were working with the police and security company that provides door staff.
'We are unable to comment further on what is an ongoing police investigation'.
"Our thoughts are with the student's family and friends at this very hard time".
