Unfortunate farce for bomb in ship

A strange man called yesterday morning in the Port Authority of Argostoli and said that a bomb had been put in the ferry Andreas Kalvos that had sailed five minutes ago from the port of Poros with destination to Killini, Peloponnese. The authorities immediately informed the captain of the ship and ordered him to return to the port. Of course, the passengers got upset but all the security measures were taken. The police, with expert dogs, searched all the rooms of the ship but they found no explosive material. One hour later, the ship sailed again for Killini. Now the police are investigating for the number of this call, that was proved to be such an unfortunate farce.
