The National Stock Exchange has warned investors about a fraudulent entity, Lazard Asset Management India, operating through a WhatsApp group called 'JO HAMBRO,' falsely claiming to be a registered stockbroker and collecting money from retail investors. Multiple individuals have been victims of similar scams, including a retired Punjab DGP tricked out of Rs 2.5 lakh by cybercriminals posing as CBI officers, and a Ludhiana man who lost Rs 52 lakh in a stock market investment fraud. Additionally, a businessman in Mumbai has been accused of cheating a relative out of Rs 2.7 crore with false promises of high returns. In Udupi, a man was defrauded of Rs 8.5 lakh through an investment scam on the 'Ship It' app. These incidents highlight the growing prevalence of online scams and the need for increased awareness and caution among potential investors.
