A man was kidnapped and held captive for months as a “blood slave” after being lured by a fake job advert.

The Chinese man, who identifies only by his surname Li, escaped earlier this month with the help of a member of the gang that kidnapped him.

The man is currently being treated in a hospital and is in a stable condition, reports the South China Morning Post.

Li was lured by a fake job advert, held at gunpoint, and taken across the China-Vietnam border.

He was sold to a Cambodian gang running the fraud scheme for £15 thousand.

Since August 2021, the gang in Cambodia took 800ml of blood each month from Li.

Guidelines for safely donating blood recommend no more than 500ml at the most per donation.

The blood reportedly was sold to private buyers online.

When he was admitted into hospital last week, Li’s arms were badly covered in bruises and needle marks.

The man who had worked as a security guard in Shenzhen and Beijing said he refused to be a part of the gang’s fraud scheme and after learning he was an orphan and couldn’t be used for a ransom, they chose to use him as a “blood slave”.

Li detailed how seven other men were detained in the same room as him.

Due to him having an O negative blood type, which the person who tested him said was “quite valuable” the gang took more blood from him than the other seven.

The man was threatened to be sold to illegal organ harvesters if he didn’t give them his blood.

The Chinese embassy in Cambodia sent staff to visit Li in hospital and said it has asked Cambodian police to prioritise the case.
