Gardaí are questioning a man in connection with alleged people trafficking in County Donegal.
The man in his 40s was arrested yesterday as part of an ongoing operation which saw six men rescued from a business premises in Letterkenny last month.
The men who were rescued in August were aged between 21 and 45. Gardaí say they are now staying at safe and secure accommodation.
Investigators searched a number of properties in Letterkenny again Tuesday.
The man they detained is being held under section four of the Criminal Justice Act and can be held for up to 24 hours.
A number of bodies are involved in the investigation including Romanian Authorities and the Garda Human Trafficking Investigation and Co-ordination Unit.
