Dhanesh Kumari, who was 8-month pregnant, died mysteriously last night, said police.
On the basis of a complaint filed by Kumari's father Abhey Singh Yadav, a case of dowry death was registered against her husband Sanjay Yadav, father-in-law Suraj Bhan Yadav, mother-in-law Shakuntala Devi and two others at the the Model Town police station today, they said.
In his complaint, Abhey, a resident of the nearby Niganiawas village, has alleged that because of his inability to give Dhanesh's in-laws a car, they tortured and strangulated her to death last night.
Postmortem examination of the body was conducted in the civil hospital here this evening and the report is awaited.
