A magistrate in Zambia on Thursday granted bail to eight Croatian nationals charged with child trafficking.

Magistrate David Makalicha in Ndola, in the mineral-rich Copperbelt province, said the eight should each pay 20,000 Kwacha (about $1,000) bail and surrender their passports to the court.

The eight were named as Damir Magic, 44, Nadica Magic, 45, Zoran Subosic, 52, Azra Imamovic Subosic, 41, Ladislav Persic, 42, Aleksandra Persic, 40, Noah Kraljevic, 45, and Ivona Kraljevic, 46, when they first appeared in court on Tuesday and pleaded not guilty to charges of child trafficking.

They are defended by a legal aid lawyer, Kelvin Silwimba. In the charges brought before the court, the Croatians are accused of attempting to traffic four named children late last year into Zambia “for the purpose of exploitation.”

Media in Croatia had reported that the detained Croats were four couples and that they included Zoran Subosic, a guitarist for well-known band Hladno Pivo, or Cold Beer.

On Thursday, witnesses included an immigration officer and a guest house manager.

Mercy Phiri, an immigration officer at Simon Mwansa Kapwepwe International Airport, said she was tipped off that some Croatians were planning to leave the country through the airport with Black children.
