A poacher fatally shot one of his closest friends during a nocturnal hunting expedition in western Greece early yesterday, in the apparent belief that he was a wild pig. Yiannis Karayiotis, 40, and Spyridon Spyrakos, 59, had set off to kill wild boar in a forest near the village of Vryssoula, north of the western town of Preveza. Under cover of night, they prepared an ambush and waited for their quarry to appear. When Karayiotis heard a rustling in the bushes, he eagerly let fly, only to hear a human cry of pain. His friend died shortly after being struck by the large-bore shot used for boar-hunting. Police arrested Karayiotis, and are investigating the precise circumstances of Spyrakos’s death. The legal hunting season for wild boar started on September 15 and ended on January 20.
