High street fashion retailer Zara is under investigation over the alleged use of slave labour at factories in Argentina, it has been reported.
Immigrant workers, including children, were discovered by the workers' rights group, La Alameda, producing clothes for the label in "degrading" sweatshop conditions, investigators claimed.
The mostly Bolivian labourers claimed they were made to work more than 13 hours a day and were prevented from leaving the factories without permission.
Garments being sewn at one workshop in Buenos Aires were said to include items from the Zara Man fashion line sold in British stores.
Juan Gomez Centurion, head of the country's health and safety watchdog, which raided three factories allegedly producing Zara clothes last week, said: "We found men and children who lived in places where they worked.
"They were not registered and they were living in terrible conditions. They had no official documents and were held against their will, they were not allowed to leave their workplaces without permission."
