Four migrant smugglers were arrested and 27 illegal immigrants were intercepted in two separate incidents on Wednesday in Thessaloniki and the port of Patras.

Three migrant runners, aged 32, 39 and 54, were arrested by police in Xirokrini, Thessaloniki as they attempted to transport nine illegal migrants, including two children, to Athens.

The three detainees had picked up the migrants from a farming area outside Soufli, in Evros region, and boarded them on a truck to transport them to Athens, with a stopover in Thessaloniki.

The money paid by the migrants for the transport was not yet know, while police were also investigating the participation of more individuals in the case.

In a second incident, the 25-year-old driver of a truck was arrested in the western port of Patras after 18 migrants lacking documents were found hidden in the semi-pickup truck as it prepared to board an Italy-bound ferry.

Police said the truck bore stolen license plates, while the driver's license was forged.
