Bhubaneswar: Four persons have been arrested from Bhubaneswar for allegedly operating a mule account supply network that helped cyber fraudsters siphon off crores of rupees across the country, police said on Saturday. Police claimed the network had links with suspected Chinese operators and used cryptocurrency, VPNs and mobile applications for cybercrime.The arrests were made during an investigation into an online investment fraud in which a Bhubaneswar resident allegedly lost Rs 91.9 lakh after being lured through a Facebook message and later added to a WhatsApp group called Finsol Insights Exchange. The victim was reportedly promised high returns on investments made between July and Aug this year but was unable to withdraw the money after transferring funds to multiple beneficiary accounts.Police identified the accused as Sai Subham Suar (24) from Keonjhar, Bhabani Sankar Roy (21), Biswajit Jena (20) and Shishir Kumar Jena (26), all from Bhadrak district. Eight mobile phones and several digital records, including transaction histories, chat logs and crypto-trading evidence, were seized from them.Police sources said the accused allegedly recruited young people to open savings and current bank accounts in exchange for commissions. These accounts were subsequently handed over to cyber fraudsters and used to receive and route proceeds from various online scams.Police said the network relied on Telegram, WhatsApp calls and VPN services for communication. Fraudsters allegedly used SMS-forwarding APK applications to remotely access devices linked to bank accounts, enabling them to operate internet banking services while concealing their identities.The probe further revealed that commissions were allegedly paid in cryptocurrency through exchanges such as Binance and later distributed among recruits and account holders. Police suspect that account details were shared with foreign operators and that fake business entities were created in some cases to open current accounts.Police said the syndicate had been active in supplying bank account kits to contacts outside Odisha, including West Bengal, where they were allegedly used in cyber fraud operations ranging from investment scams to customer care and online gaming frauds.Officials urged youths not to be tempted by easy-money schemes involving bank account rentals or digital account trading, warning that participation in such activities could attract serious criminal charges and long-term legal consequences.
