A man was kept as a 'blood slave' for six months after being kidnapped during a fake interview.
Li, from Jiangsu province, China, was snatched by a Cambodian gang in August last year after refusing to be part of their online fraud operation.
The 31-year-old, who was working as a security guard at the time, had 800ml of blood taken from him each month he was held captive.
According to local reports, his blood was then sold to private buyers on the black market.

Li told the media that he was kidnapped by the gang after going for an interview for a job with a fake company.
He was then taken to the China-Vietnam border and forced him to cross at gunpoint.
Li was then taken to Ho Chi Minh city and into Cambodia, where he was 'bought' by another fraud gang for $18,500 (£13.6k).
At the time, it is said, they had hoped to keep him for ransom.

However, after discovering that Li was an orphan, they decided to harvest his blood instead.
He said that the 'doctor' told him: "Your type O blood is quite valuable!”
Li told reporters that he and at least seven other prisoners were being held at the time, and were often beaten with electric prods by the gang.
After months of draining his blood, the gang began to struggle to get enough out of his veins.

In the end, Li said, the 'nurse' had to take blood from his head.
It was only because one of the gang members decided to help Li that he was able to escape.
When he was admitted to hospital on 12 February, his body was covered in bruises and he was close to dying from organ failure, it's been reported.
However, his condition is now stable and he is continuing his recovery in hospital.
While the human body is capable of replacing the blood taken during a donation in around 24 to 48 hours, it can take around 12 weeks to replenish the red blood cells.

It is also not recommended to donate blood more frequently than every 56 days.
