Gurgaon Police Commissioner Mohinder Lal said 10 pathology labs, five diagnostic centres, and three private hospitals have been identified as having links with the racketeers. He said Mohit Hospital in Raghupura, Noida, was possibly owned by Kumar and that some surgery may have been carried out there.

Sources in Moradabad police said that Batra Hospital, on the Mehrauli-Badarpur Road, was also under the scanner: many cases were referred to the hospital either before or after transplant surgery.

The investigation has also turned up documents of 48 requests for kidney transplants from across the world, most of them from Greece.

On Sunday night, Gurgaon police raided two premises, believed to be places where Kumar and his brother lived. The first: F-168, Omaxe Executive Floors near Sushant Lok-II. The second: C-102, Emerald Coral Court, Essel Towers, on the Mehrauli-Gurgaon Road.

“We are certain that Kumar owned six properties in Gurgaon in his own name. We are trying to identify those registered under fictitious names,” Lal said.

Investigators have also identified and frozen eight bank accounts operated by Amit Kumar and seized three cars used to ferry patients from the Gurgaon Sector 23 hospital and the DLF Phase-I guesthouse where they were lodged. But investigators are yet to trace any of the 25 persons — five nurses and 20 ward boys — they say were working at the Sector-23 house used for surgery.

“Certain precautions that needed to be taken before the Uttar Pradesh police team arrived at the clinic were overlooked,” Lal said. He also said that the Income Tax department had investigated the clinic last year. “But we were never informed, and know nothing about the outcome. Even now we are uncertain if it was a survey or a raid,” he said.

Lal said Gurgaon police are holding Amit Kumar’s driver Harpal, traced by Faridabad police, for questioning. The driver is said to have disclosed the names of some restaurants and hotels where the deal making between the racketeers and patients seeking transplants took place. But officers were unwilling to comment on his testimony.

Among other evidence obtained is a copy of one of Amit Kumar’s and his second wife’s passports, leading police to believe that the couple may have been using multiple identities. His second wife, Poonam Saini, belongs to Pathankot; police are still unsure if she was involved in the racket but are certain she was in the know of it.

Touts, a website, ads abroad
According to Gurgaon Police Commissioner Mohinder Lal, Amit Kumar and his team of doctors had touts in all major Delhi hospitals with nephrology departments. They would identify patients requiring transplants and approach them with offers.

Lal said that considering the large number of patients from abroad, there was a possibility that Kumar used the Internet extensively to make contact and strike deals. The police have identified his website and are trying to determine how it was being used.
