AMIT Kumar, also known as "Dr Horror", allegedly ran illegal clinics in India and sold kidneys for transplants to hundreds of wealthy clients from Australia, Greece, the UK, Turkey, US and Saudi Arabia.

Police say his group performed 400 to 500 kidney transplants over a nine-year period. Some donors even claimed they were forced at gun-point to undergo surgery to have their kidneys removed.

Those who sold their kidneys to Dr Kumar were reportedly paid about RM3,400 (S$1,455) to RM10,250 (S$4,387). He charged Indian kidney recipients between RM54,680 and RM136,700 for the transplants.

Indonesian Salimudin, 27, sold 7.5cm of his liver for 300 million rupiah (S$6,8629) to an Indonesian man. In June 2002, without his parents' knowledge, he was flown to Singapore for the operation at a private hospital. He said he was told to say that the recipient of his liver was his uncle.

Levy Izhak Rosenbaum, who is not a licensed physician or medical professional, offered to procure a kidney for an undercover FBI agent and a confidential witness working for authorities for US$160,000 (RM500,000).

Rosenbaum is alleged to have purchased the organs from Israelis for US$10,000 (S$13,696) each. The scheme involved bringing donors from Israel to undergo surgery to remove their kidneys.
