Eight members of an organ trafficking ring in north-east Pakistan have been arrested, police say.
The ring’s alleged leader, Fawad Mukhtar, is accused of extracting the kidneys of more than 300 people and transplanting them into rich clients.
He had previously been arrested five times for malpractice, but managed to secure bail each time.
At least three people died from having their organs harvested in this way, authorities said.
The gang was believed to be operating across eastern Punjab province, as well as in Pakistan-administered Kashmir.
The transplants were carried out in private homes – often without the patient knowing, the chief minister of Punjab province Mohsin Naqvi said.
A car mechanic is said to have worked as Mr Mukhtar’s surgical assistant and helped lure vulnerable patients from hospitals.
The kidneys were then sold for up to 10 million rupees (£99,000; $120,000) each, Mr Naqvi added.
The commercial trade of human organs was made illegal in Pakistan in 2010.
The punishment for those caught includes a decade-long jail term and huge fines in the hope that this will stop sales to overseas clients by exploitative doctors, middlemen, recipients and donors.
However, there has been a rise in organ trafficking in the country as people struggle with low wages and a poor enforcement of the law.
In January, Punjab police uncovered another organ trafficking ring after a missing 14-year-old boy was found in an underground lab after having his kidney removed.
