Former UK consulate employee, Simon Cheng, says he was tortured in China and accused of encouraging political unrest.
Whilst being detained for 15 days on China’s mainland, Mr Cheng claims he was “shackled, blindfolded and hooded”.
An interview with the British Foreign Secretary Dominic Raab revealed the UK government supports Mr Cheng and has summoned the Chinese Ambassador.
Mr Raab said they have made it clear that it is expected the Chinese authorities will review and hold to account those responsible.
"We are outraged by the disgraceful mistreatment that Mr Cheng faced when he was in detention in mainland China," Mr Raab said.
