Three men have been questioned in England as part of an on-going investigation into the seizure of almost €300 million worth of cocaine off the Cork coast last September.
The drugs were on board the yacht Makayabella, which was detained by an armed boarding party from the Naval vessel LÉ Róisín more than 200 miles off Mizen Head.
The three men, aged 27, 29, and 31, were arrested at addresses in west Yorkshire as part of an investigation by the National Crime Agency, Britain's leading law enforcement body dealing with serious and organised crime.
They were arrested on suspicion of conspiring to import cocaine into the United Kingdom and were released on bail pending further investigations.
Last week, three men were given jail sentences ranging from eight to ten years after they pleaded guilty at the Circuit Criminal Court in Cork to drug trafficking arising out of the same seizure.
Another man, Stephen Powell, described as the brains and the money behind the operation, has been jailed for 16 years in Britain for his involvement, and three others are currently before the courts there.
