Gardaí have arrested two men as part of an investigation into human trafficking and labour exploitation.
Officers in Donegal arrested the men, aged 28 and 35, on Tuesday morning for organised crime offences.
Both men are being questioned at garda stations in the county.
Gardaí, with international colleagues, are investigating the alleged trafficking of people into Ireland for the purpose of labour exploitation.
The operation involved a joint investigation team which has been established with police in Latvia. Law enforcement activity was also being coordinated in Latvia on Tuesday.
Europol officers were present in Donegal during Tuesday morning's operation.
An Garda Síochána continues to appeal to anyone who may be the victim of human trafficking or labour exploitation to speak to them.
