A MAN suspected of masterminding the attempted drug smuggling operation foiled at Dunlough Bay in 2007 has been arrested in London.

The €500m worth of cocaine seized off of the West Cork Coast remains the biggest in the history of the State.

The 45-year-old is understood to be a well-known South London criminal and one of four members of the Dunlough Bay gang who gardaí believe escaped from West Cork at the time.

He arrived at London’s Heathrow Airport yesterday from Madrid where he was being questioned by police in relation to a separate matter.

The attempt to smuggle 1.5 tonnes of cocaine into the UK via Ireland failed when a rib carrying 62 bales of the drug ashore capsized in rough conditions.

Four members of the gang are currently serving sentences in Ireland while another two are in prison in the UK.
