What guilty was Vassilis Paleokostas found before breaking out of prison?

This was one of the most daring prison breakouts to take place in Greece. The helicopter landed in a courtyard of Korydallos prison in Athens as those on board threw flares into the area. Amid the confusion, two inmates managed to climb into the helicopter which took off again, flying to a nearby cemetery. The escaped prisoners then fled with their accomplices on motorbikes which have since been found near the port of Piraes. One of the men, Vassilis Paleokostas, was serving a twenty-five-year sentence for kidnapping and bank robbery. It’s thought his brother, who’s been on the run since 1990, was behind the breakout. The police have arrested the helicopter pilot, who says he was forced to fly to the prison at gunpoint.Korydallos holds some of the country’s most notorious criminals, including the leaders of the militant left-wing organization, November Seventeenth, who were found guilty of murdering politicians, businessmen and foreign diplomats.
