Police have rescued more than 100 people they say were locked in a rice-processing factory and forced to work throughout a coronavirus lockdown.
From the end of March the men were allegedly not allowed to leave the mill in the northern city of Kano in Nigeria.
The workers were promised an additional $13 (£10) a month on top of their $72 monthly salary – those who did not accept were threatened with the sack.
The men said they were threatened with sack by the managers of the Indian-owned mill, Popular Farms.
Policemen stormed the factory on Monday after obtaining a court injunction, arresting four managers and releasing the detained workers.
