The transplant surgeries were done mostly in Kiev, Azerbaijan and Ecuador.An Israeli suspected of heading the trafficking ring was arrested last month.In April, six people were arrested in Israel by the northern branch of the police's National Fraud Unit for allegedly misleading people into donating their organs in exchange for false promises of money, and for arranging dangerous organ transplants abroad that resulted in medical complications for recipients.The ring allegedly placed ads in local newspapers promising $100,000 to kidney donors. In some cases, those allegedly duped by the ads were paid only $10,000, while in other cases, the organ donors received no money at all. In 2008, the Knesset outlawed organ trafficking and the earning of profit on organ transplants. The law stipulates that all organ transplants must be carried out by the National Transplant and Organ Donation Center.
