The mayor of the southern Italian town of Riace, who is famed for taking in migrants, has been placed under house arrest over allegations he facilitated "marriages of convenience" for immigration purposes. Domenico Lucano is known for his warm reception of migrants, a policy that stands in stark contrast to that of Italy's current populist government. Lucano has long supported a program that welcomed migrants to his sparsely populated town, where they have been given abandoned homes and occupational training in an effort to revive the local economy.
