Two inmates have been found dead in their cells at Malandrino Prison, authorities said yesterday as they awaited the results of autopsies to determine how the inmates died. The dead men were not named but authorities said they were both Greek and were serving 15-year and four-year sentences for drug offenses. One was 38-years-old and the other 22. An internal investigation was launched immediately but authorities at the prison in Fokida, central Greece, said it was likely that the men had overdosed on drugs. Their bodies were found in their cells by prison guards shortly after the convicts returned to the jail. One prisoner had just returned from a five-day furlough while the other had previously appeared in court for sentencing. Malandrino Prison was at the center of recent protests by inmates which sparked riots in at least nine prisons around the country. The convicts were demanding better conditions in Greece’s overcrowded jails.
