Police identified the two men arrested as Sachin, resident of Shahpur in UP, and Lokendra who lives in Bawana, Delhi. The three who fled have been identified by police as Farooq, Mahendra and Jugnu.

DLF Phase II police station SHO Kailash Chand said Jugnu, who worked as a carpenter and knew the layout of the apartment complex and its residents, was the gang informer. He had once worked in the Block 18 apartment that was targeted, Chand said.

The men gained entry into the premises after telling guards at the gate that they were from the Delhi Vigilance Bureau. They even wore jackets with Delhi Police painted on the back.

“The incident took place around 10 pm on Wednesday. Police reached the spot immediately after they were informed. We picked up the duo and arrested them after an inquiry. Investigations are on,” DCP (East) Maheshwar Dayal said.

Police recovered a Santro car, a countrymade revolver, a pistol, live cartridges, a chain and Rs 1,600. They also seized masks, ropes and red chilli powder.

“Cases have been lodged against them. We are investigating if this gang was involved in other incidents of robbery,” SHO Chand said.
