Nine people have been arrested during raids on suspected illegal workers at shopping centres in Northern Ireland.
The operation targeted mobile phone accessory stalls in 19 locations.
They included shopping malls in Belfast, Bangor, Londonderry, Lisburn, Newtownards, Armagh, Portadown, Dungannon and Enniskillen.
The raids were carried out by Home Office criminal investigation and immigration enforcement teams, assisted by PSNI and Police Scotland officers.
Mike Golden from the Home Office said: “It was one of the largest operations that we’ve done in Northern Ireland.
“We may prosecute and we will certainly look to, where we can, remove people who shouldn’t be in the UK back to their home countries.”
Mr Golden said more arrests could take place in the coming days.
