A South African performance artist who tied a live rooster to his penis during an impromptu open-air show near the Eiffel Tower was found guilty today of "sexual exhibitionism", but the Paris court did not impose a sentence, prosecutors said.

Last September Steven Cohen danced on the tourist-filled Trocadero Plaza dressed in a corset, high heels, long red gloves and an elaborate feathered headdress with a rooster attached to his penis by a ribbon.

Against the backdrop of the Eiffel Tower, and under the amused and perplexed gaze of tourists, including a group of nuns, the spectacle lasted only a few moments before police arrested Cohen, dragging him across the plaza, rooster attached.

Cohen's lawyer told Reuters she was "relieved".

"This is a rather measured decision," said lawyer Agnès Tricoire. "In my opinion, this case should never have gone to court."

In a March interview with Le Figaro daily, Cohen said authorities had "no understanding of what art is, what performance is".

"If I'm found guilty ... I will see it as a failure of French justice," said Cohen, who has lived in France for about 10 years.
