A group of drunk females on the infamous Carnage student pub crawl told a homeless man to "get a f***ing job" before dragging him to the ground, pulling down his trousers and punching him in the face and body.
The university students were asked for change by the man, prompting them to launch the vicious attack, which included one woman kicking him in the face, according to a Daily Mail reporter who witnessed the attack.
The group were on a Brazilian fancy dress night out organised by Carnage UK, which has already had its fair share of controversy. One student even "blacked up" for the event, and has allowed himself to be named in the picture on the Cardiff Carnage Facebook page.
A previous pimps and hoes fancy dress theme in 2012 sparked a petition to ban the "misogynistic" event, but the company shrugged off the allegation. At the same event, Manchester students decorated their Carnage t-shirts with Nazi Swastikas and messages of support for the BNP and IRA. At a similarly-themed playboy vs bunnies night which took place in February earlier this year, large groups of women were pictured in various states of undress, again raising concerns Carnage nights were sexist.

In 2009, student Philip Laing was warned he faced jail after urinating on a war memorial during a Carnage night out. The previous year, Bath University student Gethin Bevan was found hanging from a tree the morning after participating in one of the organisation's pub crawls.
A spokesperson for South Wales Police said: Chief Inspector Steve Benson-Davison said:
"While the (Carnage) event results in high numbers of intoxicated individuals generally there are no major issues in terms of violent crime and disorder.
"Enquiries are continuing into an assault on a man in St Mary Street on around 10pm."
A spokesperson for Carnage said: "The company promotes/advertises fancy dress events for more than 250,000 annually. [It] does not promote or condone the commission of criminal offences.
"The majority of event attendees are well-behaved people who come to socialise with their friends and enjoy the variety of fancy dress themes and music genres provided at the different venues.
"The company always works with the police to assist in identifying any minority of individuals who may have been involved in wrongdoing."
