New Delhi, Sep 12: A 70-year-old retired Income Tax officer was found killed inside her residence here Wednesday, said police adding that robbery seems to be the reason behind the incident.

The incident was reported around 4.15 p.m. Wednesday from flat number D-11/67 in west Delhi's Rohini Sector-8.

Gurjeet Kaur, who resided alone in her flat, was found killed.

"The victim's neighbours informed police about the incident after they found her dead. Her hands and legs were tied with ropes while her mouth was shut with a tape," said a police officer.

"As the whole house was found ransacked, it seems to be a case of robbery," added the officer.

A case of murder has been registered and the hunt is on for the culprits
