In 1970s Britain, Chinese-heritage migrants worked long hours in restaurants and takeaways to build their new lives. But as the diaspora established itself, the gangs they thought they’d left behind in Hong Kong began to follow, quietly feeding off the very people they claimed to protect.

Back in Hong Kong, Georgie Pai was already a senior member of Wo Shing Wo, one of the most feared Triad societies operating in the city’s underworld. Known for its rigid hierarchy, blood-sworn loyalty and a reputation for ruthless enforcement. He travelled to the UK on a tourist visa and began working at his parents’ takeaway in Glastonbury. From there, he united scattered Triad factions around the country and recruited loyal foot soldiers. He soon built an extortion network targeting Chinese communities, with business owners ordered to pay protection cash. Those who refused were brutally punished.

From the back alleys of Hong Kong to the neon-lit Chinatowns of Britain, Georgie Pai built a nationwide criminal empire through his Triad gang Wo Shing Wo. With a network of protection rackets, gambling dens and an army of loyal followers, he controlled his turf with threats, violence and machetes. Gangster steps inside the world of the Triads. A brotherhood bound by secret handshakes and elaborate rituals, where loyalty is sworn in blood. For decades, Georgie Pai’s name alone caused absolute terror amongst Britain’s Chinese community. He was deported back to Hong Kong several times, but with police unable to pin him to a single crime, it was left to a team of journalists to bring him down.
