A 66-year-old Greek man was arrested on the Athens-Lamia highway on Monday after he was found to be hiding 30 undocumented migrants in the concrete mixer he was driving.
Police said that the driver had picked up the 30 migrants in Evros, northeastern Greece, and was planning in return for a payment of 4,000 euros.
Nine of the migrants were Somalian. The rest were Syrian. The group included five minors, aged between four and 15.
