SINGAPORE: 12 foreign workers were locked up in their scrap metal factory along Defu Lane since last Wednesday.
The factory's boss is reportedly away and will only be back this Thursday.
Police and officials from the Ministry of Manpower arrived at the factory to break the lock.
The workers, from India and China, are entitled one day off every week.
But during this festive season, they were not granted this privilege and had to stock up their food supplies for a week, on Lunar New Year eve.
The workers added that their bosses did not even leave any contact number.
Authorities are investigating the case.
Wrong confinement of persons for three days or more may result in imprisonment of up to two years or a fine, or both. - CNA/vm
