A student has apologised after being caught on camera urinating over a city centre war memorial.
Philip Laing, 19, will appear before magistrates in Sheffield later this month charged with outraging the public decency.
He was one of around 2,000 students taking part in the Carnage UK event on Sunday evening, during which many drunken scenes were caught on camera.
The students paid £10 each to take part in the drinking session.
Laing was reportedly in a "shocking state" and curled up for a sleep in front of a shop window, only to be woken by a group of giggling girls.
He was allegedly helped to his feet and walked over to the First World War memorial in Baker's Pool, where he relieved himself over tributes left to the fallen.
The incident was reported to security staff who washed down the memorial with buckets of water.
Laing issued his apology through Sheffield Hallam University.
He said: "I am deeply ashamed of this photograph and I am sincerely sorry for my behaviour.
"I have no recollection of the events in the photograph, although I recognise that this does not excuse my actions.
"I apologise unreservedly for any offence I may have caused."
Superintendent Peter Normal, of South Yorkshire Police, said: "The behaviour portrayed in this photograph is disgraceful and will not be tolerated.
"As soon as it was brought to police attention, officers began the process of tracing him so that he could be put before the Magistrates Court.
"Similar student events are a regular occurrence in Sheffield and are usually very well-run and well-organised by the Students' Union and the event organisers.
"Incidents of this nature are a very rare occurrence.
"Unfortunately, on this occasion, one individual has brought shame upon himself and damaged the reputation of the event and the organisers."
Participants who paid the £10 each got an official T-shirt and access to a series of clubs and bars, though they bought their own drinks.
Everyone involved was invited to wear "doctors and nurses" fancy dress.
Carnage UK is run by Birmingham-based Varsity Leisure Group Ltd, which operates similar events for students across the country.
A statement from the group said: "VLG has the greatest respect and admiration for all those who lost their lives in the defence of this country.
"VLG is appalled to see this individual (or any individual) treating a monument to commemorate those people in a disrespectful manner.
"The perpetrator of this despicable act will not be welcome at future events held by Carnage UK."
