"The accused came inside the showroom as customers, on the pretext of buying jewellery. They held the employees captive, threatened to shoot them and decamped with valuables," they said.
They even took the digital video recorder of the CCTV cameras, the police said.
Police are probing whether the accused were also involved in another robbery in northwest Delhi's Adarsh Nagar, in which a jeweller was shot dead in front of his son.
