Interpol issued international warrants on Friday for the arrest of two key accused in the multi-crore kidney transplant racket in Haryana as they are suspected to have escaped from the country shortly before the police conducted raids.

The 'red corner' notices against alleged kingpin Amit Kumar and his brother Jeevan were issued following request from the Central Bureau of Investigation after Haryana Police discovered an illegal hospital at a house in Gurgaon near Delhi where the transplants were allegedly carried out.

Police has alleged that during the past eight years, around 500 people were forcibly operated on and their kidneys were transplanted to patients, including foreigners. Kumar (40) and Jeevan (36) "are both subject of national arrest warrants for illegally transplanting kidneys, cheating and criminal conspiracy," the Interpol warrants said.
