At least four people are expected to face organised crime charges or extradition to Spain as part of an international investigation into drug trafficking.
Yesterday in Dublin over 50 searches were carried out on homes and businesses suspected of being used to launder millions of euro.
Further searches are to be carried out today. A total of 34 people were arrested in Spain, the UK and Ireland. Eleven have been released in the UK without charge.
Britain's Serious Organised Crime Agency have said that
The nine men and two women arrested in the UK have been released pending further enquiries in Britain and elsewhere.
Officers from the Garda National Drugs Unit are examining computers, files, paperwork and records seized in raids in Dublin and Meath.
Along with accountants and solicitor offices, hairdressers, dry cleaners and shops were also searched.
Detectives believe these businesses were being used to facilitate the laundering of drugs money.
Gardaí have already discovered a bank account with €200,000 in the name of a man with no means to earn this amount and a betting scam used to launder €2.5m on which tax was paid and only €200,000 was lost.
Spanish national police are continuing to question convicted drug dealers Christy Kinahan and John Cunningham. The authorities there believe they will have sufficient evidence to charge them.
They are working closely with the gardaí and along with the UK Serious Crime Squad are sharing information and evidence for use in prosecutions in all jurisdictions.
Gardaí have also identified four individuals - senior members of the gang in Ireland - who they expect will either be extradited to Spain or face organised crime charges here.
