BENGALURU: Around 23,000 complaints had been filed against Md Mansoor Khan , founder-owner of I Monetary Advisory (IMA) and its officials by Thursday evening and estimates of the money swindled in the ponzi scam targeted at Muslim investors, ballooned to over Rs 1,500 crore. The IMA proprietor, the prime accused, flew out of the country last Saturday, June 8, a day before the first complaint was filed against him, police sources told TOI . Bengaluru city police have issued a lookout notice for Khan.All complaints so far have been attached to the first complaint made by Khalid Ahmed, Mansoor's close friend and business partner, sources said, who accused Mansoor of cheating him of Rs 4.8 crore. Barely 24 hours after Khalid's complaint, an audio clip, purportedly of Khan claiming he was on the verge of committing suicide , was widely circulated on WhatsApp. The clip blew the lid off the scam and thousands of investors rushed to Commercial Street police to file complaints. By then, Khan was long gone, police said."Khan was alone when he cleared immigration around 6.40pm. His flight to Dubai took off at 8.45pm," sources in the state secretariat said. "His associates recalled how Khan was tense since central agencies were communicating with the state, prodding why no action had been taken against him and his firm. Earlier on Saturday, he himself drove his favourite Jaguar to the Kempegowda Airport."Khan's Jaguar (KA 05 MW 41) and Range Rover (PY 05 C777) were seized from the Shivajinagar residence of Nizamuddin Azeemuddin, one of seven IMA directors arrested on Wednesday."Khan flew to Dubai on an Airbus business class seat," police said.
