Delhi Police have arrested a software engineer and two associates for allegedly running a large-scale investment fraud using a fake online trading platform. The scam is estimated to have involved up to Rs 100 crore, police said.

The case came to light after a resident of Paharganj filed a complaint, stating he was cheated after investing through an online trading platform. Police registered a case and began an investigation.

During the probe, police arrested Ravi Rathore, who they described as the key planner behind the operation. Investigators said he quit his job at a multinational company, where he was earning an annual salary of around Rs 30 lakh, and went on to set up the fraudulent platform.

According to police, the accused lured hundreds of investors across the country by promising double returns. A fake website and mobile trading app were created to collect funds, which were then transferred to multiple bank accounts.

Police said complaints increased when promised profits did not materialise. The three accused are in custody and further investigation is under way.
