POLAND - Police in Poland are investigating the execution-style murder of a Russian artist and vocal critic of President Vladimir Putin.

Polish prosecutors said Robert K, known as the artist Semyon Skrepetsky, was shot dead on Monday morning in the Polish city of Biała Podlaska, about 40km (25 miles) from the Belarusian border. The 44-year-old was shot five times in the head, chest and back in a car park in the city, located about 600m from the Belarusian consulate. Semyon Skrepetsky was the pseudonym used by Robert Kuzovkov. He was known for his caricatures of politicians, including Putin, Belarusian leader Alexander Lukashenko and Chechen leader Ramzan Kadyrov. Marcin Kozak, spokesman for the District Prosecutor's Office in Lublin, said the artist was approached by an unidentified gunman who fired two shots at him. "When the victim fell to the ground, the perpetrator approached, fired three more shots and then quickly fled the scene. Robert K died at the scene," he added. Five shell casings and one Geco 9mm Luger bullet were recovered from the crime scene, Kozak said. An autopsy has been scheduled for Wednesday. (BBC)
