Gurugram, Aug. 2 -- Four suspects, including a woman, were arrested from an apartment in Sector 86 on Thursday for allegedly posing as Delhi Police Special Cell officials, barging into the flat, holding four occupants hostage and assaulting them in a bid to extort Rs.25 lakh, Gurugram police said on Saturday. Sandeep Turan, public relations officer of Gurugram police, said the woman was sent to judicial custody, while the three other arrested suspects were remanded in police custody for four days after being produced before a court on Friday. "Three forged Delhi Police identity cards, seized from their possession, were arranged by their fifth aide , also from Rohtak, who is on the run," he said. Police said the origin of the forged identity cards is under investigation. The suspect believed to have arranged them is absconding, and further details are expected after his arrest. Police said the suspects failed to extort any money as their plan was foiled before the cash could be collected. Investigators said one of the victims secretly shared his live location and alerted a friend via WhatsApp, who arrived with several others instead of bringing cash, forcing the accused to flee. Police said the fifth aide allegedly planned the crime after learning that one of the victims belonged to a financially well-off family. The incident took place on Wednesday night at an apartment in Tower A of Ansal Heights Society in Sector 86, rented around six weeks ago by the complainant, a resident of Police Colony in Delhi's Kalkaji, who was hosting a get-together with three friends. According to the FIR, a woman rang the doorbell claiming to be a neighbour before entering with seven men posing as Delhi Police Special Cell officials. "They said it was a raid on a tip-off of illegal activities while displaying their identity cards and assaulted all four when he opposed their activities and threatened to put us inside jail," the complainant alleged. Police said one victim was forced to travel towards the Delhi-Gurugram border on Dwarka Expressway to arrange Rs.25 lakh before the plan was foiled. An FIR was lodged at Kherki Daula police station under BNS sections 191(2) (rioting), 190 (unlawful assembly), 115(2) (voluntarily causing hurt), 308 (extortion), 204 (personating a public servant), 319(2) (cheating by personation), 127(2) (wrongful confinement) and 351(3) (criminal intimidation). Police said raids are underway to arrest the remaining three suspects....
