Peter William Humphrey (born March 1956), commonly known as Han Feilong (Chinese: 韩飞龙) in China, is a British former journalist and private detective, known for his arrest by the Shanghai Police due to allegations that he illegally acquired personal data of Vivian Shi, a Chinese citizen with connections to the Shanghai communist elite.

In 2003, he founded a risk management company called ChinaWhys (Chinese: 中慧),[6] whose websites claimed to provide creative solutions to tricky business problems in China.

[8][9] In March 2013, secretly filmed sex videos of Mark Rilley, GlaxoSmithKline's then head in China, were emailed to 13 senior executives of the company, including the CEO Andrew Witty.

[10][11] According to The Sunday Times, the videos were accompanied by detailed accusations of the company's "pervasive bribery" in China made by an anonymous writer called "gskwhistleblower".

[11] Since April 2013, ChinaWhys was paid by British drug maker GlaxoSmithKline to investigate into the source of the sex tapes.

Ofcom later upheld a complaint that CGTN's UK broadcast of this violated their fairness and privacy regulations.

[18] The court ruled that Humphrey should be imprisoned for two and a half years and fined 200 thousand RMB before being deported from China.

[9] Although his wife Yu Yingzeng was a US citizen, the court considered her personal and criminal circumstances and did not expel her from China.

[12] Yu said she never knew acquiring third-hand personal data was illegal in Mainland China and admitted they had done similar investigations in Hong Kong and other areas.

[23] After returning to the UK, Humphrey maintained his innocence and argued that his confession was forced and the broadcast footage by CCTV was doctored.

[29] Guang Shuang, China's Foreign Ministry spokesperson, denied that there was forced labor at Qingpu.
