A man has been jailed after been found guilty of secretly filming dozens of women urinating at a music festival in Denmark.

The 49-year-old German was found to have recorded as many as 60 women at the Roskilde Festival using a camera hidden inside a beer can.

The defendant claimed he did not know what he was doing was wrong as the women were urinating in public.

His lawyers tried to argue that the women had essentially forfeited their right for privacy, saying that some of them sat "relatively close to" the defendant and "even sat there and smiled", reported Ritzau.

The Danish court dismissed the claims, with prosecutor Anne Oxbøll saying his offences were even worse as he was paid to make the recordings by a man who gave him the beer can.

"It is an aggravating circumstance when you record things for payment from another man without knowing if they are going to be distributed online," she said.

Videos of women urinating at the Roskilde, one Europe's largest music festivals, often end up appearing on fetish and pornography websites, according to The Local.

The 49-year-old has now been jailed for 30 days. Judge Tove Horsager told the court: "The accused was fully aware that the women had not agreed to the recordings in that the recordings where made with a camera that was elaborately built in to a beer can and the films were of high quality."
