A 32-year-old woman from Durgapur in West Bengal's Paschim Bardhaman district died in Sweden where she was pursuing post-doctoral research, her family said. Alleging that the victim, Roshni Das, was murdered, her family has sought the Central government's help in launching a probe into the matter and bringing her body back home from the Scandinavian country. Roshni studied zoology honours from Burdwan Raj College and biotechnology from Kalinga University in Bhubaneswar, Odisha, before moving to Sweden, it is learnt. Her family members, who live in Durgapur's DPL Township, said they last spoke to her on September 29 and could not establish any contact with her thereafter. It was on October 12 that the Swedish authorities contacted the Indian embassy and informed them about her death, they said. The family was informed that her body was recovered from inside an apartment and a Swedish national has been arrested in this connection. Roshni's brother Supratim Das said, "On October 13, we got the news that she was found dead in an apartment. Then we contacted the local MP. As far as I know, a citizen of Sweden has been arrested. The body has been kept in a morgue for now. We are completely in the dark about the reason behind the murder.” “The embassy staff do not know much on this but they are in contact with the local police. We want the Indian government to ensure the culprits get an exemplary punishment,” he added. Surinder Singh Ahluwalia, Bharatiya Janata Party MP from Burdwan-Durgapur, said, “The Swedish authorities will not release the body right now as an investigation is going on in the matter. I haven't received any official document yet. We hope we will get them by next week. We can start the process to bring back the body only after that."
