A woman was burnt allegedly by her husband in Mymensingh on Sunday.
Police said Shirina Akter (22), mother of a one-year-old son, was initially taken to Mymensingh Medical College Hospital (MMCH).
Shirina lived with her husband Sohel Mia, two step-children and the man's first wife in Pungai village under Tarakanda upazila, said the law enforcers.
Sohel, a day labourer and son of Suruj Mia from Pungai, married Shirina, daughter of Siraj Ali of the same village, four years ago, Tarakanda Police Station Md Abul Khayer quoted the family and locals as saying.
There has been a dispute between Sohel and Shirina over dowry since their marriage, said the OC.
In the afternoon on the day, Sohel beat her indiscriminately as she refused to bring money from her father, said the police officer, adding that, at one stage, he burnt her pouring kerosene on her.
Hearing her screams, neighbours rushed to the spot and took her to MMCH. Shirina sustained more than 70 percent burns, the police officer quoted MMCH doctors as saying.
Later at night, Shirina's family sued Sohel, his mother Phuly Begum (50) and sister Sheuly Begum (20).
Following the case filed with the police station, the law enforcers arrested Phuly and Sheuly, said OC Abul Khayer, adding that Sohel has been on the run since the incident.
As Shirina's condition deteriorated she was transferred to the burn unit of Dhaka Medical College Hospital yesterday, said the police officer.
Meanwhile, a Mymensingh court sent the arrestees to jail when they were produced before it, the OC said.
