Delhi Police said the victims were lured by the human traffickers on the pretext of providing jobs.
Some of the victims were staying in the two-room flat for the past three months and they alleged that they were compelled to work in nearby houses under pressure.
Delhi Police conducted raids on the direction of the National Commission for Protection of Child Rights (NCPCR) in cooperation with a Delhi-based NGO, Mission Mukti Foundation.
Police said the victims were brought to the national capital by Santosh Srivastava, who ran an agency named QR Placement Cell.
“He has been running the agency for the past three years,” police said.
The victims have been sent to shelter homes.
Police are now trying to get in touch with the families of the minors to send them back to their homes.
