MumbaI, Oct. 18 -- A 40-year-old jewellery designer was kidnapped and assaulted by a man who claimed that the victim had borrowed gold worth Rs.76 lakh from him. In an attempt to recover the gold, the accused confined the victim, identified as Khokan Mandal, overnight in a Parel flat and also extorted Rs.3.14 lakh from him before releasing him the next day. So far, the police said six accused have been arrested and one is still absconding. The incident took place on Tuesday night when Mandal was sitting outside his building. He was approached by three men and a woman, who told him he was wanted in a case and must go with them to the Dadar police station. When Mandal resisted, they forced him into a car and took him to a flat in Parel. "At the flat, Mandal was confronted by two men he already knew, Tarak Maiti and Raghunath Maiti. They assaulted him and demanded that he return their gold," said a police officer. Mandal told them the jewellery was stored at his workshop, which was closed for the night. The accused continued to beat him through the night and, on Wednesday morning, forced him to call his employees and arrange for 600 grams of gold, valued at around Rs.76 lakh, to be brought to the flat, he added. The accused also demanded more money. Mandal transferred Rs.15,000 online, but since his transfer limit had been exhausted, they allegedly forced his staff to bring a cheque and made him sign a cheque of Rs.2.99 lakh, before releasing him. The police investigation has revealed that the Maiti brothers had allegedly hired Mahadik, one of the accused in the case, to recover the gold from Mandal....
