A doctor from Zakynthos has been arrested and police are looking for a secondary school teacher from Crete in connection with the storage and distribution of child pornography.

The electronic crimes squad said they moved in on the unnamed suspect on Zakynthos following a seven-month investigation that involved foreign police forces. The teacher has not been arrested because he is away on vacation, sources said.

The two men are suspected of collecting and exchanging hardcore pornography involving children. Officers are investigating possible links to pedophiles in Greece and abroad and say there may be more arrests.

Over 20 people were arrested in Greece two months ago as part of an international crackdown on child pornography.
