UK Border Force officer was ‘working for China’, court told

A landmark trial at London’s Old Bailey has unveiled disturbing allegations of foreign interference, revealing what prosecutors describe as a Chinese “shadow policing” network operating within the United Kingdom. Chi Leung “Peter” Wai, a serving UK Border Force officer, and Chung Biu “Bill” Yuen, a retired Hong Kong police officer working at Hong Kong’s Economic and Trade Office in London, stand accused of conducting surveillance operations against Chinese dissidents on British soil.

The prosecution, led by Duncan Atkinson KC, presented evidence suggesting the defendants operated as if “Pontefract were a town in China rather than Yorkshire.” The court heard how Wai, leveraging his privileged access to the Home Office’s Atlas immigration database, allegedly conducted unauthorized searches on Chinese citizens, particularly those with pro-democracy backgrounds who had sought asylum in Britain.

Evidence presented to jurors included surveillance reports detailing extensive monitoring of targets, with one woman, Monica Kwong, becoming a primary subject of investigation. The operation allegedly involved teams entering apartment buildings, examining personal mail, and conducting covert filming—including footage of Kwong answering her door in pink pajamas with her young son.

Communications revealed Yuen coordinating with Hong Kong-based police officer Wing Cheun Cheuk, while referring to Wai by the codename “fatboy” in messages. The prosecution emphasized this represented “a further misuse of the database… not for legitimate UK purposes but for the benefit of persons in Hong Kong.”

The case took a tragic turn with the death of Matthew Trickett, a second Border Force officer allegedly involved in the surveillance network, who was found dead in May 2024 after being released on bail. Evidence suggests Trickett assembled additional operatives, including former military personnel, to expand the monitoring operations.

Both defendants deny charges of assisting a foreign intelligence service and foreign interference. Wai additionally pleads not guilty to misconduct in public office regarding his database searches. The trial is expected to continue for six to seven weeks, potentially setting significant precedents for how Western nations address foreign interference operations within their jurisdictions.
