MUMBAI, Feb. 20 -- A 74-year-old Cuffe Parade resident was cheated to the tune of Rs.50.8 lakh by a cyber fraud who posed as a doctor from New Zealand and claimed to be working with the United Nations (UN) peacekeeping force in Yemen. The police said the fraud befriended the senior citizen through social media and asked for the money claiming he needed it to save his daughter. According to the south cyber police, the case has been registered based on a complaint by the victim, a Cuffe-Parade resident. The police said the fraud began in January, when she met an unknown man on social media. The man identified himself as Joshua Willian and claimed to be a doctor from New Zealand working for the UN. The man told the woman that he was posted in Yemen for peacekeeping duties, said a police officer. "He told her that his daughter Maya and several other children had suffered food poisoning after eating a birthday cake and some of them had died. He said, Maya survived but was in a critical condition and needed an urgent surgery to save her life," said the police officer. After his repeated requests, the woman sent him a total of Rs.50.8 lakh in 27 online transactions between January 5 and February 3 this year, said the police officer. He even told her that he would return her money when he came to India after his peacekeeping assignment in Yemen was over. On February 9, the fraud called the woman again and told her that he needed more money. When she asked her son for help, he asked her why she suddenly needed money and she narrated the entire episode to him. He immediately realised that she had been defrauded and asked her to report the incident to the police. Based on the woman's complaint, the police have registered a case against the unknown fraud under relevant sections of the BNS and IT Act....
