The accused, identified as Sahil (24) and Jamal (22), used to cheat people by allegedly promising them huge returns in exchange of US dollars, police said.
The matter came to light on October 4, when a Sangam Vihar resident lodged a complaint that he was cheated by a person named Ravi, who induced him to earn huge money in exchange of US dollars, they said.
