The man, who is being detained at Dundalk Garda Station, is the third person to be arrested as part of Operation Joggle after two men were arrested in March.
In 2018, several premises were raided across counties Laois, Louth, Meath, Kildare and Dublin by gardaí investigating a west-African gang suspected of laundering €14.6 million through bank accounts here.
