Authorities on Majorca are cracking down on pub crawls after last week's incident in which an 18-year-old girl from Co Armagh was seen performing sex acts on more than 20 men in public.
The incident, during a pub crawl in the popular resort of Magaluf, was filmed and the video has appeared on social media.
The mayor of Calvia, the region that includes Magalluf (inset) and five other resorts popular with Irish holidaymakers, said yesterday he had passed a law "giving us tighter control over the operation of pub crawl organisers".
Manuel Onieva also said a police investigation had begun into last week's incident, adding that he wished to "express my total rejection and anger at the activities which were carried out in a video which is currently on the social media circuit".
The pub crawl is believed to have been organised by Majorcan-based company Carnage Magalluf which describes itself on its website as the "leader in Magalluf party entertainment".
The company advertises a three-event package for £79.99 (€100) including "bar crawl, boat party and jungle sessions".
The bar crawl is a four-nights-a-week event that includes "four hours of unlimited drinking, four hours of unlimited free shots and a free Carnage vest/T-shirt".
Mr Onieva said: "Companies operating pub crawls in Calvia now have to apply for a licence through the town hall.
"They have to prove their responsibility and show they have the appropriate civil insurance.
