Kolkata: Howrah resident Saurish Naskar (27) was arrested on Tuesday for duping a New Town resident, Uttam Kumar Singh, of Rs 11 lakh. Naskar had contacted Singh on social media and convinced him to invest through a Demat account, promising high returns. Singh was added to two WhatsApp groups—VIP 71 Genius Innovation Capital Group and DS Genius Innovation Capital —and tricked into transferring Rs 11 lakh. On realising, he had lost the money, Singh filed a complaint on National Cyber Crime Reporting Portal on March 7 and a FIR at Bidhannagar Cyber PS on April 22. tnn
