A man accused of organising a "shadow policing" operation on behalf of China has denied ordering surveillance of Hong Kong dissidents in the UK.
Giving evidence at the Old Bailey on Monday, Chung Biu "Bill" Yuen, a former Hong Kong police officer, also told jurors how a dissident protestor had cursed his "whole family to die".
He said he had never tasked Chi Leung "Peter" Wai - a former UK Border Force officer with whom he is standing trial - with spying on dissidents in London.
Both men, who have British and Hong Kong passports, deny charges of assisting a foreign intelligence service and foreign interference.
Wai, who previously worked for the Metropolitan Police and was a volunteer Special Constable with the City of London Police, also denies a charge of misconduct in public office in relation to conducting searches of Home Office databases.
