Majorca authorities are cracking down on pub crawls after last week's incident in which an 18-year-old from Northern Ireland was seen performing sex acts on more than 20 men in public.
Footage of the incident, involving a teenager from County Armagh on a pub crawl in the popular resort of Magaluf, appeared on social media sites.
The mayor of Calvia, the region which includes Magaluf and five other resorts popular with Britons, said 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".
Manuel Onieva said today he had passed a law giving "tighter control over the operation of pub crawl organisers", adding that companies operating pub crawls in Calvia "now have to apply for a licence through the town hall" and must "prove responsibility".
"Pub crawl groups can now not exceed more than 50 people and if any operators exceed this legal capacity, they will be fined," he added.
