Central Bureau of Investigation (CBI), the Indian agency investigating into international kidney transplant racket allegedly led by Dr Amit Kumar, has requested details of his property, bank accounts, investments and other assets, apart from the number of transplant surgeries conducted by him in Canada.

A CBI team may also visit Canada for further probe. The Canadian authorities are already in touch with the Indian investigating agency.

Dr Kumar was arrested from Nepal in February last year after he fled from India following registration of case against him.

Investigations into the illegal kidney transplant case had led to Brampton in Canada, where Dr Kumar had a house.

The case called attention to medical tourism, the practice of traveling abroad for health care at more affordable rates.

The Indian doctor would allegedly charge US$50,000 for a kidney transplant. The clandestine racket served international clients from Britain, the US, Greece, Lebanon, Canada, Saudi Arabia and Dubai. He is believed to have carried out 500 illegal kidney transplants amassing wealth worth several crores of rupees.

The racket flourished by conning or forcing people from underprivileged sections to relinquish their kidneys to wealthy clients. The ring used scouts to spot potential marks.

He ran an illegal hospital in Palam Vihar in Gurgaon. As his profession prospered in India he invested money in Canada eventually settling his wife and son there.

Canadian police located the house in Brampton following a request by Indian police via an Interpol "red notice". His wife and two young children stayed there. The doctor purchased the 5,600 sq ft home in February 2007 for C$610,000. Subsequent upgrades performed at the home included an in-ground pool, at a cost of C$100,000. The family lived luxuriously with the children studying in private school. The family drove expensive SUV.

The Indian Enforcement Directorate has already attached properties allegedly belonging to the racketeers across the country and abroad. Amit Kumar allegedly had a hotel in Santa Cruz in Mumbai, a hospital in Gurgaon in India besides a number of flats and bungalows. Some of his properties were identified in Hong Kong and Australia besides Canada.
