MADRID—Spanish police raided three clandestine tobacco factories early this year, seizing nearly 40 million euros ($44 million) worth of tobacco leaf and illicit cigarettes.
At one, in the northern town of Alfaro, they found 10 Ukrainian workers, five of them war refugees, who'd been put to work with no contracts and scant pay, police said. They worked all day for and lived at the factory, forbidden from leaving.
