The woman, Manjula Devak, a PhD student in water resources, was found hanging at her flat around 7.30 PM on May 30.
Her family had claimed that her in-laws used to torture her and were not in favour of her pursuing her PhD and instead wanted her to return to their home in Bhopal.
They had claimed that her husband Rajesh Virha, whom she had married in 2013, asked her to arrange Rs 20 lakh so that he could start a business.
Police said they will be questioning her in-laws and husband in the matter.
