Athens police arrested three Bulgarians who were brokering the sale of Bulgarian babies in Greece, television station bTV said.
The group was arrested while allegedly in the process of exchanging an infant for money, the report said.
The group had been operating in the area of Lamia, a city in central Greece.
It was led by a man from Varna and one from Yambol.
The head of Greece’s anti-people trafficking department said that the ringleader of the group persuaded women to become pregnant, or who were pregnant, to then go to Greece to give birth in public hospitals.
After the babies were born, they were sold to childless Greek families, allegedly for about 1000 leva (about 500 euro).
Another channel involved prostitutes who were pregnant, the report said.
The alleged ringleader was subject to a European arrest warrant and, according to Greek authorities, was meant to be serving time in a Bulgarian prison.
