Police rescued the girls, aged between 15-18 years, from GB Road with the help of NGO Shakti Vahini and Rescue Foundation on a tip off.
Three of the rescued girls are from Nepal, one from Maharastra, one from West Bengal and one is from Karnataka.
During investigation, police said, it was revealed that they all belong to poor families and they were lured on the pretext of providing them good employment in Delhi.
"They are being produced before Child Welfare Committee, Delhi for taking further course of legal action," Devesh Srivastava, Additional Commissioner of Police (Central), said.
