Mohali, Aug. 14 -- A businessman residing in Mohali's Aerocity area has alleged that he has been receiving extortion calls from persons claiming to be members of the Lawrence Bishnoi gang. Complainant Gurinder Singh said the callers have been demanding Rs.10 crore, threatening to kill his family members if he failed to pay up. He told the police that he runs an education office in Chandigarh's Sector 47, where his father and brother Narinder Singh also work. On July 7, around 7.15 pm, he received a call from a foreign number. The caller claimed to be Goldy Dhillon from the Bishnoi group and asked if he was Bhagwan Singh. When Gurinder replied that he was Bhagwan Singh's son, the caller listed the names of other family members, gave their home and office addresses, and demanded Rs.10 crore. On July 8 and 9, he received more calls from the same number, which he ignored. Soon after, he got a life threat via a WhatsApp message. On July 13, at 7.45 pm, Gurinder's mother received a ransom call on WhatsApp from the same number. The threats continued, and on July 14, another caller, claiming to be from the "Bokson Bishnoi group," conveyed a "special message" from Anmol Bhai, again demanding Rs.10 crore. The extortionists sent photos of the family's house and vehicles via WhatsApp. Aerocity police have registered a case against Goldy Dhillon of Muktsar and Hari Bokson of Sonepat, under Sections 308/2 (extortion), and 351/2 (coercion) of Bharatiya Nyaya Sanhita....
