Two dozen customers at a Thessaloniki strip club were treated to an unexpected variation on the program early yesterday when a couple of armed men shot up the premises with semiautomatic rifles. Police arrested an ethnic Greek immigrant from Georgia, who held at bay the doorman of the Caligula Club, near the Macedonia Airport on the outskirts of Thessaloniki, while his two accomplices burst in. The gunmen, who are also believed to be Greeks from Georgia, began shooting into the air with Kalashnikov rifles. Customers, waiters and dancers dove for cover while the gunmen – probably gangsters trafficking in women from Eastern Europe – tried to drag off a Russian stripper. But police border guards, who happened to be driving through the area, heard the shots and pulled up to investigate.The gunmen ran away through the fields, while Ignatios Basanasidis, 23, was arrested.
