Moscow police said they pressed slavery charges against a Vietnamese co-owner of a sweatshop who allegedly employed 700 slaves. The suspect, along with seven others, is accused of running an illegal factory in a Moscow suburb. Illegal migrants staffed the warehouse, and the sweatshop owners had seized their documents to prevent them from leaving, RIA Novosti reported. The co-owner, whose name is not being released, faces 10 years in prison if he is convicted. Police raided the factory in July as part of anti-migrant raids, but some suspects avoided arrest, RIA Novosti reported.
