A 36-year-old woman was found dead inside her rented accommodation in Rohini, police said on Sunday.

On Friday, Rohini South police station received information that a woman was found dead in her room in the second floor of a building in Mangolpur Kalan village, following which policemen rushed to the spot, they said.
The woman was a resident of Agra in Uttar Pradesh, police said.
Initial enquiry revealed that she was residing in the house with a man, who is also a native of Agra, believed to be her live-in partner for over 10 days. The house owner informed that he had last seen the two around 6.30 pm Thursday, a senior police officer said.
On Friday around 10.30 am, when the owner came at the second floor, he found the door of woman's room partially open and her body motionless, the officer said.
During inspection, no external injury mark found on the body, which has been preserved in BSA Hospital mortuary, he said.
