Greek authorities have held the pair for over 70 days without trial, alleging they were conducting military espionage. Bohemia says they weren't working for ArmA 3 but on vacation.
Czech Republic president Václav Klaus has written a public letter to Greek president Karolos Papoulias in the hope of getting some favourable legal traction on the charges.
"I would like to address a matter of two Czech citizens who were arrested in Greece and charged with espionage," began president Václav Klaus, translated by . "This case is very sensitive to the Czech public and also to me as President of the Republic. The fate of our citizens anywhere in the world matters to us."
"I have no doubt that the democratic Greek authorities - police, prosecutors and the courts - will consider this unfortunate matter impartially and independently. Even I do not in any way want to interfere with their work."
"I want to ask you, Mr. President, to follow this unfortunate affair with special attention considering the excellent relations between our nations so this does not throw unnecessary shade onto our relationship," he continued.
"Once again, I want to assure you that I have the utmost certainty that our accused citizens will be given all the rights in the search for justice by the Greek authorities." A public demonstration is being organised in Prague to bring further attention to the plight of Ivan Buchta and Martin Pezlar. It's being rallied by Daniel Vávra, a creator of 2K Czech's Mafia.
