A «mysterious user of Facebook, Baller Boyz, on November 22», wrote something concerning a gamble and a motorbike (la Repubblica.it).
«The rider posted a photo» on the social network and «bet he would ride naked through Münster’s Christmas market but only if the photo got 1,000 “Likes”» (The Local.de).
No sooner said than done. Our man looses the bet. Therefore, on December 15, he «strips off completely before mounting the bike» and he starts «his tour of Münster», only wearing his helmet, gloves and shoes.
The police opened «an investigation into the case», but identifying the biker will probably be not so easy (ibidem).
