PRAYAGRAJ, May 2 -- Cyber fraudsters duped a woman from Jayantipur Sulemsarai of Rs.20 lakh by luring her with the promise of tripling her investment through online trading within 12 days. The fraud was allegedly carried out by an unidentified woman who first befriended the victim on Facebook. Dhoomanganj police have registered a case and launched an investigation with assistance from the cyber police unit. According to a written complaint filed by Preeti Khanna, she came into contact with a woman on Facebook a few days before the incident. During their interactions, the accused gained her trust and later persuaded her to invest in a cryptocurrency trading website. The complainant alleged that between April 10 and April 22, she deposited a total of Rs 20 lakh in multiple installments on the website suggested by the accused. As per the purported agreement, the portal showed a profit of Rs 68 lakh on April 22. However, when Preeti Khanna attempted to withdraw the amount, she was asked to pay an additional Rs.14 lakh as a withdrawal fee. When she expressed her inability to pay the demanded fee, the entire balance displayed on the trading portal suddenly disappeared, showing zero. Around the same time, the woman who had introduced her to the platform cut off all communication and became untraceable. Dhananjay Pandey, station house officer of Dhoomanganj police station, confirmed that a case has been registered in the matter and said further investigation is underway with technical assistance from the cyber police team. Police officials are examining digital evidence and bank transaction details....
