Simon Cheng Man-kit (Chinese: 鄭文傑; born 10 October 1990) is a Hong Kong activist. He was formerly a trade and investment officer at the British Consulate-General in Hong Kong. Cheng was detained by Chinese authorities in August 2019 in West Kowloon station when he returned from a business trip in Shenzhen. While the Chinese authorities stated that he was arrested for "soliciting prostitutes", Cheng denied the accusation and added that Chinese agents tortured him in an attempt to make him confess that he was a British spy who was involved in instigating the 2019 Hong Kong protests. Cheng subsequently fled to London and was granted asylum in June 2020.
