In February 2008, another kidney transplant center, run by a man called Amit Kumar, was discovered by police in Delhi and nearby Gurgaon. Due to technological advances in fingerprinting, Kumar and Raut are now believed to be the same perpetrator, having gone by many aliases throughout years of illegal activity. Kumar is facing charges for his decades of involvement in illegal organ trade, which includes over 600 illegal kidney transplants and the involvement of at least two hospitals.[37]
