The Nagpur-based recipient is a businessman and he is believed to be in a severe financial crunch after paying for three (including his own) kidney transplants in his family.
The recipients based in Jammu and Jaipur are small time entrepreneurs, said an official privy to the investigation.
While a 22-year-old Ghaziabad-based man, identified as Ashutosh, who is the son of a DJB junior engineer, was arrested on Thursday, another recipient who had produced forced documents showing his address as Ghaziabad before the transplant has been traced in Delhi, the official said.
DCP (southeast) M S Randhawa said, "Recipients in the first five cases have been identified. In other five, we have leads but the identities are yet to be established. Efforts are on to arrest them at the earliest."
The police have arrested 13 persons, including several middlemen, personal assistants of senior doctors, donors, a recipient and the racket's kingpin Rajkumar Rao, in connection with the matter so far.
