How the racket was busted

Jaideep Sharma, whose friend went missing, poses as a kidney donor, requests a television channel to conduct a sting

The channel informs Delhi Police

The channel begins recording the dealings; police stay as backup to ensure Sharma remains unharmed

Once the two teams collect sufficient evidence, police swoop down on the hospital minutes before Sharma was to be operated

Police conduct multiple raids across the city to arrest four alleged middlemen

Role of doctors and staffers at Batra Hospital and a city-based diagnostic centre is also under the scanner.
