Ten people have been arrested after two workplaces were searched by the Garda National Immigration Bureau.
Six of those were arrested at the warehouse of an Asian food products supplier and a number of attached offices in a business park in West Dublin in January.
Three people were arrested on foot of live deportation orders.
The others were arrested for having no legal status to be in the State and appeared before Blanchardstown District Court in January, where they were remanded until 13th March.
Department of Social Protection officers also suspended a number of welfare payments potentially saving the State €100,000.
Following a second search at a Meat Processing company in Co Meath on the 11th of February, four people were arrested and charged under immigration legislation, while a fifth person claimed asylum.
A further 11 people were found not having any current immigration status in the State, and will be deported.
