Ten people have been arrested over the last month in west Dublin and Meath following workplace searches by the Garda National Immigration Bureau (GNIB).
Two searches were conducted by the GNIB in conjunction with the Workplace Relations Commission (WRC) and the Department of Social Protection on January 30 and February 11.
The first operation took place at the warehouse of an Asian food products supplier and a number of attached offices, in a business park in west Dublin.
It was established by the GNIB, following investigations and intelligence gathered, that the company was suspected of employing persons in contravention of immigration and employment permits legislation.
It was also established that a number of persons who were subject to deportation orders were being employed at the business.
Three people were arrested on foot of live deportation orders and three others were arrested for having no legal status to be in the State. They subsequently appeared before Blanchardstown District Court on January 31, where they were remanded until March 13.
The Department of Social Protection officers suspended a number of payments, including disability allowance, rent supplement and child benefit, with an estimated potential savings of 100,000 euro to the State.
The second search operation took place at the offices and warehouse of a meat processing company in Co Meath.
A total of 19 individuals were discovered in contravention of either immigration or permit legislation.
Four people were arrested and charged under immigration legislation. They were subsequently granted bailed to appear at Swords District Court on Wednesday and Balbriggan District Court on February 27, while a fifth person claimed asylum.
An additional 11 people did not have any current immigration status in the State and will be subsequently deported in accordance with legislation.
A further three non-EU nationals were interviewed due to possible discrepancies in relation to work permits.
The WRC is continuing to investigate to ensure compliance with employment legislation at both warehouses.
