Dr Ramesh Chada - a nephrologist at Gandhi Hospital, Hyderabad, and his two assistants - PS Praveen and Prasanth have been booked.
Police arrested two brokers who allegedly helped Dr Chada to get many victims who were targeted by the group led by the doctor.
According to sources, the accused used to bring the victims to Indu Superspeciality Clinic which is run by Dr Chada at Karkhana in Hyderabad.
Dr Chada and his group have been accused of luring poor people to make a huge amount of money by transplanting kidneys illegally.
The sting operation was carried following a complaint by Yadagiri, a resident of Medak district. The complainant approached the police on May 3. The police officials later stated, "He said he was offered Rs 5 lakh after he offered his kidney to an unrelated donor. According to the deal, he was to be paid an advance of Rs 1 lakh before the operation, and the remaining amount after the transplant surgery."
However, cops have already started an investigation and lodged an FIR in which the two brokers - Venkata Srinivas, an employee of SVR Travels at Lakdikapul and Rajendra Prasad alias Rajendra Kumar, a medical insurance agent of Khairatabad along with the two assistants of Dr Chada have been named.
All accused have been booked under the charges of cheating and violation of the AP Human Organ Transplantation Act.
