A man was arrested in Donegal as part of an investigation into an Organised Crime Group (OCG) suspected of being involved in drug dealing and money laundering offences.
The man in his 30s is currently being detained at a station in the Garda North Western Region under Section 50 of the Criminal Justice Act 2007.
More than 100 Gardaí conducted a search operation in Donegal, Sligo and Monaghan, and in Tyrone in conjunction with the PSNI, as part of the investigation.
The searches were conducted at 15 residential addresses in east Donegal and Letterkenny, four in the Sligo Town area, one in Monaghan and one in Laois.
Searches were also conducted in Tyrone by the Police Service of Northern Ireland.
Led by Detectives from the Donegal Division, this operation was supported by the Garda National Drug and Organised Crime Bureau (GNDOCB), the Armed Support Unit (ASU), the Garda Dog Unit and detectives from Sligo and Monaghan.
More than €26,000 in cash, £12,000 in sterling and quantities on cocaine, cannabis and tablets – with an estimated street value of €40,000 – were seized by Gardaí, as well as mobile phones and other electronic devices.
Investigations are ongoing.
