A former U.K. border official and a retired Hong Kong police officer were sentenced on Thursday to prison for spying on dissidents and critics of Beijing in Britain, a case that lays bare how state power reaches across borders to monitor people who dared to organize, protest, and seek sanctuary.
Peter Wai, a Border Force officer, and Bill Yuen, a former superintendent in the Hong Kong Police, were found by a jury last month to have breached the National Security Act by assisting a foreign intelligence service. At London’s Central Criminal Court, Judge Bobbie Cheema-Grubb sentenced Wai, 41, to 10 years and Yuen, 66, to eight years in prison.
The targets were not powerful people. Prosecutors said the pair posed as police or intelligence officers to conduct surveillance and gather information about Hong Kong dissidents and pro-democracy supporters. Their targets included former Hong Kong lawmaker Nathan Law and activists they referred to as “cockroaches,” along with British politicians critical of China.
Who Was Watched
The people under surveillance were described by prosecutors as dissidents, pro-democracy supporters, and critics of Beijing. Helen Flanagan, commander for Counter Terrorism Policing London, said the pair were “spying and targeting individuals in the U.K. who were pro-democracy campaigners and were simply protesting against the Hong Kong and Chinese government and authorities and seeking sanctuary in the U.K.”
That is the hierarchy in plain view: people fleeing repression and speaking out were tracked by men with state credentials, one from the U.K. Border Force and the other tied to Hong Kong’s police apparatus. Wai was also convicted of misconduct in a public office for using a government computer to seek information on people of interest to the Hong Kong authorities.
Judge Cheema-Grubb said the defendants’ “deliberate, concerted, and serious” actions had left those targeted in fear and distress. The sentence followed convictions last month, when the jury found both men guilty under the National Security Act.
The Machinery Behind the Case
Wai’s position inside the U.K. state was not minor. He had been an officer in London’s Metropolitan Police before joining the U.K. Border Force. Yuen was office manager at the Hong Kong Economic and Trade Office in London, described as the official overseas representative of Hong Kong’s government.
The case also pulled in diplomatic machinery. Chinese Ambassador Zheng Zeguang was summoned to the British Foreign Office after the convictions last month. At the time, China’s Embassy in the U.K. called the case a political farce intended to support anti-China forces who had fled to Britain.
The Hong Kong government rejected the allegations, saying they “are absolutely unrelated” to the government or the Economic and Trade Office. It said British authorities “initiated the case on groundless accusations, abused law and manipulated judicial procedures to secure conviction.”
Those statements sit alongside the facts of the case: a government computer used to gather information, a public office used for surveillance, and a foreign intelligence service assisted through covert monitoring of people already under pressure. The legal system processed the case through a jury verdict and prison sentences, while the people targeted were left to absorb the fear and distress described by the judge.
What the Sentences Mean
Wai received 10 years in prison and Yuen received eight years. The convictions came one month ago, and the sentencing took place on Thursday at London’s Central Criminal Court.
The case shows how state institutions can be used not only to police borders, but to extend surveillance toward dissidents and pro-democracy supporters far from home. It also shows how those with access to official posts can turn public authority into a tool for tracking people who were, by the prosecution’s account, simply protesting and seeking sanctuary.
