UK authorities have seized more than two tonnes of cocaine in a raid on a luxury yacht off the coast of southern England. British authorities said they arrested six people on Thursday evening after discovering the drugs with an estimated street value of £160 million ($221 million) on a Jamaican-flagged yacht sailing from the Caribbean. One British man was arrested on suspicion of drug trafficking, along with five Nicaraguans. The National Crime Agency (NCA) released photographs of the drugs stored in black waterproof bags in the lounge of the docked <i>Kahu</i> yacht. "There's no doubt these drugs would have been sold on into communities across the UK," said NCA deputy director Matt Horne. The seizure "will smash a hole in the organised criminal gang's plans and ability to operate," he said. The NCA said it intercepted the yacht when it was 130 kilometres off the coast of the port of Plymouth after receiving evidence from a sting operation by the Australian Federal Police, who participated in the raid. This summer the Australian police and the FBI revealed they had carried out an operation persuading criminal networks to use supposedly encrypted phones called Anom that were in fact copying messages to law enforcement authorities.
