The police was informed about illegal immigrants on board a train travelling from Istanbul to Aderna, Anadolu Agency (AA) quoted security sources as saying.

The sources said that the police arrested 27 illegal migrants while searching the train, adding that the migrants were intending to infiltrate Greece.
