Delhi police on Tuesday arrested two men, including an UPSC aspirant, from Delhi’s GB road for allegedly raping a teen girl and then trying to sell her off in a brothel.

According to a senior official of central district, a police constable deployed in plainclothes spotted a man, later identified as Parvej, roaming about suspiciously in the area.

The constable, Sundar, posed as a procurer and gained Parvej’s confidence. Parvej told him about his intention of selling a 15-year-old girl.

“Sundar convinced him of setting up a deal and called the Kamla Market SHO Sunil Dhaka. Dhaka posed as Kotha owner to fix the deal, which was finalised for Rs 18 lakh,” said a senior official of central district. “Parvej’s partner, identified as Soiab, was asked to bring the girl and were overpowered by policemen,” the official said.

Parvej, a private cab driver, told police that he and his friend lured the girl from her native place in Muzaffarnagar. Pravej raped her in his vehicle in the Loni area in Gaziabad. His partner Soiab, who is preparing for his UPSC exam, had been holding the teenager hostage since then.
