In August 2013, Greek police arrested a German citizen on the island of Chios on suspicion of spying for Turkey. Police said they had found in the man's possession cameras, laptops, maps and glasses with an embedded camera, and an email he had sent to an unidentified recipient with details on Greek warships and army vehicles on the island. The man confessed he had photographed barracks and other military-related buildings on the island for five people he believed were Turkish nationals who paid him up to 1,500 euros ($2,000) for each assignment. Greek authorities suspected that the individuals worked for the Turkish secret services.
