CCTV footage showing two students in a steamy clinch at a university ball promoting safe sex has been leaked online.
The video was recorded in the University of Exeter's Ram bar at the annual event, at which most students wear only sexy underwear, and spread across campus like wildfire.
It was today being investigated by the Students' Guild after the four-minute CCTV clip of a male and female student frolicking at a table was apparently recorded on a smart phone and posted online.
The pair are seen fondling each other at a table before the girl performs a sex act on the boy, in ‘the video everyone is talking about’ at the university.
Police say those involved in the sexual activity may have committed an offence, along with those who leaked the footage online.
One male student said he was concerned ‘people can go into the monitor rooms and put footage of us all at university on the internet’.
Hundreds of students went to the Safer Sex Ball in December, where they were handed free contraceptives.
The Safer Sex charity Aids awareness ball has been running for more than 20 years, raising up to £30,000 each time for charity.
A Guild spokesman said: 'The Students’ Guild recognise that confidential CCTV has been filmed without permission. The Guild is making sure the affected parties will be supported during this difficult time.
'Measures were in place to provide high levels of security but we are aware that irresponsible behaviour has taken place and we are working hard to rectify the situation.
'A full investigation is underway in which action proportionate to the seriousness of the situation will be taken.'
The University was also recently forced to closed down its Exeter Uni Confessions site where students submitted their most 'disgusting and hilarious confessions'.
Devon and Cornwall Police said it was not investigating the sex tape because there has been no official complaint.
A spokesman said: 'If it was reported to us, we would investigate, but it looks like the university is dealing with it internally.'
Organisers came under fire for choosing a tribal theme - dubbed racist by some students.
A student called Charlie Timms said at the time of the ball: 'I just wanna get naked and smash some birds.'
A Devon and Cornwall police spokesman said: 'Putting CCTV footage on the Internet without permission could contravene the law. That would namely be data protection laws and human rights legislation - the right to privacy.
'Engaging in sexual activity in a public place could also constitute an offence, depending on the form of sexual activity. But we would have to see the footage in question to officially comment on the incident itself.'
Chris McGovern, chairman of the Campaign for Real Education, said parents would be 'appalled' by the actions of the romping students.
Mr McGovern said: 'It's regrettable when a university has to go along this particular path in the name of promoting safer sex.
'This is rather decadent and more reminiscent of something out of the decay of the Roman Empire.
'We're in favour of safe sex but this is not the way to go. They should be focusing on their learning for heaven's sake.
'I would have thought it would only discredit the university and I think many parents whose children are at this university will be appalled.'
In 2006, the university banned initiation ceremonies after fresher Gavin Britton drank himself to death in an alcohol game based on golf.
Gavin, 18, downed beer, cider, whisky, vodka and alcopops in the pub crawl with 16 fellow students.
He wore fancy dress and had to knock back drinks in a 'par' number of gulps just six weeks into his course at the university.
Gavin, of Barton-on-Sea, Hants, visited 13 pubs and clubs in three hours, downing drinks in each.
The student, who dressed up in a Borat-style black wig, was found dead the next morning after he choked to death on his own vomit.
Speaking later, his parents Ian and Susan said: 'We hope lessons can be learned from our tragedy.'
