Mangal and Manoj were arrested from north Delhi recently after police received complaints that the duo have been cheating people.
A fortnight ago, Manoj went to Rana Partap Bagh and met Mohan Singh, a Dhaba owner, posing as a cop and stated that their boss has been transferred and wants to sell his four gas cylinders.
"The deal was done for two cylinders for Rs 4,000 and Mohan was at BBM Depot, Mukherjee Nagar with rickshaw. When Mohan came, as per the deal they took Rs. 4,000/- from him and told him to wait there but they run away in the street by cheating him," a senior police official said.
During investigations, police came to know that the duo had cheated a delivery boy of Indane Gas Agency of Rs 6,000 through the same modus operandi.
