The victim's younger sister has alleged that the victim took the extreme step after police refused to lodge a complaint and demanded a proof of the offence from her.
The victim was living in a rented house in the city with her 30-year-old sister. Four days back, her brother - Lakhan Batham - approached the sisters and asked them to live with him at their parental house in the city which they refused, police said.
Lakhan then went to their residence in Ladhedi locality of the city and allegedly sexually assaulted his elder sister on Tuesday night.
Yesterday, the sisters approached police to report the offence. However, the victim's sister alleged that the police not only refused to lodge an FIR but also used foul language, besides demanding a proof of rape from the victim.
Subsequently, the woman hanged herself to the ceiling at her home yesterday. Gwalior Superintendent of Police Santosh Singh today ordered an inquiry into the incident.
