Morigaon SP Aparna Natarajan said 11 people, including a woman, had donated kidneys so far. “We have asked for relevant documents from the state committee that gives go-ahead to donors for the transplant, and the investigation will proceed accordingly,” she said. Donors themselves are guilty of misrepresentation before the committee, she also said, adding, “But then, they are victims too, and will be our witnesses. They are poor and fell prey to temptation.” Krishna Das had sold off a kidney to repay a bank loan she had taken to run her family with her long-ailing husband. She was not given the promised amount, though. “They promised me Rs 4.5 lakh, but gave only Rs 3.5 lakh,” she said.
