All five members of the gang belong to West Bengal and have admitted their involvement in several cases of dacoity, including the recent case of robbery at a house in north-west Delhi's Mukherjeee Nagar area.
"The police received a tip-off that the gang would come to commit a robbery in east Delhi's Geeta colony area yesterday and laid a trap accordingly," said DCP (east) B S Gurjar.
While five gang members -- identified as Saddam, Lambu, Burhan, Suhail and Miraz -- were arrested, one Ainul Haque managed to escape and is still absconding, police said.
