The body of 39-year-old Bali alias Fiza Mohammad, a former Assistant Advocate General of Haryana, was found lying on her bed in her residence with several insects roaming over it, SHO Kulbir Singh said.
A senior police officer said the body found in a ground floor bedroom was in a decomposed state and preliminary inquiry showed that she may have died four to five days back.
"At this stage nothing can be stated on whether it is a case of suicide," the officer said.
No suicide note has so far been recovered, police said.
The police opened the house after neighbours reported foul smell coming from there.
Bali hogged limelight after her marriage with Chandermohan a few years back when he was Deputy Chief Minister of Haryana.

However, after his controversial marriage Chander Mohan was disowned by his father and former Chief Minister Bhajan Lal.
Having remained incommunicado for several days, the couple had resurfaced after embracing Islam and Bali changing her name to Fiza and Chander Mohan to Chand Mohammed.
Relations later soured between the two and Fiza joined politics by launching a political outfit.
Sources said that she was planning to join BSP.
Chander Mohan had recently buried his differences with his younger brother Kuldeep Bishnoi and joined the HJC headed by the latter.
In the 2009 assembly elections in Haryana, Fiza had vigorously campaigned against the Bhajan Lal family which was contesting from Adampur in Hissar district.
