A BRITISH MAN WANTED by American authorities for spying for China, who disappeared along with his Chinese handler while under house arrest, may have managed to escape to China using a private jet, a report claims. John Miller, 63, from Tunbridge Wells in the United Kingdom, was arrested alongside his alleged Chinese handler, Cui Guanghai, in April of this year.
At the time of their arrest, the two men were staying at the Hyatt Regency Hotel in Serbian capital Belgrade. Serbian authorities reportedly arrested the men just hours before they were about to board a flight to China. American authorities accuse Mille, who lives permanently in the United States, of attempting to smuggle “sensitive […] military technology” to China, such as drones, air defense systems, and ground-to-air missiles.
The two suspects were jailed while awaiting extradition to the United States, where each faced up to 40 years in prison for violating the United States Arms Export Control Act. A month later, the two suspects were moved out of jail and placed into house arrest in two separate apartments in Belgrade. Both were required to wear electronic ankle bracelets at all time.
However, on August 4, the two men damaged and forcibly removed their surveillance devices. Records show that the devices stopped transmitting their location coordinates between 12:43 and 12:54 a.m. local time. Alarms were automatically triggered, alerting officials at Serbia’s Criminal Sanctions Enforcement Directorate, whose surveillance systems were monitoring the two men.
In less than an hour, however, the two men had arrived at Belgrade’s Nikola Tesla Airport. According to a new report, published last week by the Serbia-based Balkan Investigative Reporting Network (BIRN), the suspects boarded a private Gulfstream G550 jet that was waiting for them at the airport. The report claims that the jet is owned by a Beijing-headquartered firm called Deer Jet. Shortly afterwards, the jet took off for a nine-hour direct flight to the Chinese capital.
Miller and Cui have not been seen since. BIRN said officials from the Serbian government did not respond to calls for comment. British newspaper The Mail on Sunday said it contacted Deer Jet but received no responses. The Department of Justice and the Federal Bureau of Investigation in the United States refused to comment as well.
