Six people were arrested on Friday, suspected of taking part in a scheme to recruit migrants from reception centres and put them to work illegally in the fields of southern Italy, police said. The detentions in Calabria [...] were the first under new legislation meant to stamp out the exploitation of workers, many of them refugees, in the agriculture industry... Investigators found around 30 migrants [...] each paid 15-20 euros ($22) a day off the books for 10-hour shifts... Interior Minister Marco Minniti said inspectors would visit all of Italy's reception centres over the next few days... Anyone found guilty under the legislation brought in last year can be jailed for from one to six years and fined 500-1,000 euros for each worker recruited.
