Mohd Salim Khan (25) a resident of Bharatpur, Rajasthan was arrested from near Rajokari Flyover, NH-8 on Tuesday by the Crime Branch of Delhi police following a tip off.
Investigators have recovered one pistol with two live cartridges from his possession.
"We had received information that Khan, the leader of 'Tatlu Gang' is involved in inducing and luring innocent people of Odisha, J&K and other states on phone for selling fake gold bricks/biscuits at half rates, after projecting the same as genuine gold.
Khan used to make numerous phone calls randomly on phone numbers of Odisha, J&K and other remote states of India by posing himself as Rahul Sharma, an extremely poor labourer of Rajasthan engaged in digging work at different lands acquired by ASI (Archaeological Survey of India) near Yamuna river behind Taj Mahal, said Yadav.
The accused used to lure his targets by saying that during the course of digging in the ruins near Yamuna, behind Taj Mahal in Agra, he had discovered some very ancient gold bricks of Mughal era and he was willing to sell the same at half rates compared to the market.
