The gang allegedly kidnapped the physically challenged girl and her elder sister from Jharkhand. Both the girls were rescued from the clutches of the racketeers. The arrested have been identified as Saleem (32), Pinku (24), Sumeer (38) and Sanjit (28), all residents of Jharkhand.

"One Jai Singh used to bring poor women from Jharkhand, Bihar, eastern UP, Orissa and West Bengal on the pretext of getting them suitable jobs in Delhi.

"But instead of getting them employed, he used to sell these women to various local agents like Saleem, Rajkumar, Pinku, Sanjit and Sameer after getting handsome amount," H G S Dhaliwal, Deputy Commissioner of Police (South), said.

They also allegedly used to sexually abuse the women they brought from other states, he said adding, in case, any woman tried to raise voice against this exploitation, they used to suppress it forcibly.

The arrests came following police receiving a call that some persons were trying to abduct a woman in a Maruti van near HDFC Bank in Defence Colony.

"A team rushed to the spot and found a 20-year-old woman from Jharkhand in distress. She told us that one Jai Ram who is resident of her neighbouring village came to her parents and informed that her elder sister whom hew had brought to Delhi to work as domestic help is not well.

"He requested her parents to send her to Delhi to look after her sister. However after reaching Delhi, Jai Ram allegedly sold her on January 31 to Rajkumar, Saleem and Pinku for Rs 10,000. She was handicapped," Dhaliwal said.

On the pretext of taking her to meet her sister, Rajkumar, Saleem and Pinku took her in a room in Gurgaon where they forced her to consume liquor and tried to sexually assault her, but she managed to save herself.

"The same process was continued for next 2-3 days also as they could not find a suitable buyer for her. On February two, she got suspicious and on the pretext of drinking water, she jumped out of the running vehicle infront of HDFC Bank and cried for help. The accused tried to pull her back but could not do so due to the bravery displayed by the victim," Dhaliwal said.

Saleem and Pinku were arrested from Gurgaon on February five following which the elder sister who was sold to Sanjit and Sameer, owners of K K Enterprises in Shakurpur, were rescued.
