The Oshiwara Police have arrested four men for allegedly running an online investment scam that duped a Mumbai resident of Rs 5.72 lakh by promising double returns through stock-market trading. 

The case was registered after complainant Raju Madan Mohan Chhibber received a call from an unknown number on September 20, urging him to invest in a scheme that would “double his money”. Trusting the offer, he transferred the amount over several days before realising he had been cheated.
