The British nongovernment organization Fair Trials International yesterday expressed «grave concerns» following the detention in Attica’s Korydallos jail of a 21-year-old British student of Cypriot origin who is awaiting trial for the manslaughter of a British teenager on the Ionian island of Zakynthos. «We are horrified that this young man has today been transferred to this infamous prison,» the group said in a statement, noting that Korydallos has been condemned by Amnesty International. Andrew Symeou, from Enfield in North London, was extradited to Greece in July charged with the manslaughter of Jonathon Hiles who died after falling off a podium in a Zakynthos nightclub in May 2007. Symeou has claimed that the evidence linking him to the death of the 18-year-old has been fabricated. He is alleged to have punched the victim.
