In a rare case of parallel cyber frauds, two separate gangs duped a 50-year-old former banker from Matunga of over Rs 23.17 lakh — both operating simultaneously under the guise of stock market investment schemes. 

The victim was lured through Facebook ads into downloading fake mobile apps and joining WhatsApp groups that promised high returns. By the time he realised the trap, he had already transferred Rs 23.17 lakh across 24 transactions, police said.
