Kalpana, 26, a resident of Uttar Pradesh's Rae Bareli, was found hanging from her room in her in-law's house in Meethapur area. Her in-laws took her to a nearby hospital where doctors declared her dead. Hospital authorities then informed police about the incident.
Kalpana married Sandeep Kumar four years ago and resided with her in-law's family.
Sandeep Kumar is presently posted at the New Delhi railway station.
Her brother, Sajjan, registered a police complaint against her in-laws, alleging that she might have been murdered and the death made to seem a suicide. However, her husband's family denied the allegations.
"She had been tortured for dowry since after her marriage. Her in-laws used to beat her for dowry. Three days before her death she was also beaten up," he alleged in the complaint.
Kalpana's family told police that at the time of her marriage, they gave Rs.5 lakh dowry. But, the in-laws' next demand came within few months after her marriage.
A case of dowry has been registered against victim's husband, and in-laws and inquiry into the case is on to find out the exact reason behind her death, said a police official.
