Those arrested were identified as Satyanarayan (28), Sunil (27), Ramkumar (24), Ramkalesh alias Rithik (19), Arvind (27) and Mohamad Zahir (27). All of them belonged to Madhubani in Bihar.
The arrested women were identified as Madhuri and Manju alias Poonam, both 20 years old and hailing from Odisha.
Deputy Commissioner of Police Summit Kumar told reporters that the arrests were made by the Crime Branch early on Monday.
The officer said Satyanarayan headed the gang and was known to Manju alias Poonam, who worked as a domestic help in DLF Phase II.
They were planning to rob Poonam's employer's house on the basis of information provided by her.
Poonam had served sedative-laced food to members of the family. But police nabbed the gang before they could commit the crime.
Two pistols, cartridges and iron rods were seized from the gang.
Satyanarayan reportedly shifted to Gurugram this year after being released from Delhi's Tihar jail.
