In the UK three people die every day waiting for an organ transplant. People from ethnic minorities face a particular shortage of donors - the NHS aims to achieve 80% consent rates by 2020, but at the moment only 34% of families from ethnic minorities consent to donate organs when asked, and rates of living donation have started to fall.

File on 4 finds that a small number of patients are so desperate they will risk their health by looking for a kidney abroad. Most British patients head to Pakistan, where an equally desperate group of people are coerced into giving up their kidneys, placing their lives in the hands of organ traffickers.

But now a new, sinister trade is emerging in Pakistan. In October Pakistani police raided an apartment building in Rawalpindi and behind a metal grill, found 24 terrified people locked inside. They had been lured with offers of jobs, but when they arrived were kidnapped and told a kidney would be removed.

As a worldwide shortage of organs fuels an increase in transplant tourism, Allan Urry, working in conjunction with local journalist Nosheen Abbas hears from the people caught up in this illegal trade and asks whether enough is being done to prevent it.
