The police raided the residence of the Chinese in the Jabi area of Abuja and took the unidentified couple and their domestic employees to the station.
In footage provided by the International Centre for Investigative Reporting, the victims said they had been locked up in the apartment since February.
A lady, who did not give her name, said the domestic workers were not allowed to move out of the building and that the couple refused to allow her to go for treatment when she took ill.
She stated, “When I was seriously sick, I asked these people (Chinese employers) to open the gate for me, but they refused until I became very angry before they opened the door. I know my life may be at risk but I don’t mind, let the world know what is happening.
“They told us that if someone was going out, he could help buy something for us, but when this man (referring to a colleague) went out to buy sachet water, they deducted his salary. What do they want us to do?
“We had to stay in the room and talk to people through the windows. They didn’t give us food; apart from the salary, they didn’t give us anything; they even cut our salaries.”
