A 22 year-old woman died last night four days after her husband and mother-in-law set her on fire in Kabiler Para area of Gaibandha.

Sharmin Akter, 22, died at Sheikh Hasina National Institute of Burn and Plastic Surgery around 10:00pm, said Mahfuzar Rahman, officer-in-charge of the Gaibandha Sadar Police Station.

He added that Sharmin's husband Korban Ali, 25, and his mother Kulsum Begum, 45, had a fight over trifles on Tuesday afternoon, and around 1:00pm Korban and Kulsum poured an inflammable substance on Sharmin's body and set her alight.

Police arrested the suspects and a court sent them to jail the next day, the OC said.

After the incident, Sharmin's family members rescued her and took her to Gaibandha General Hospital around 9:00pm.

A medical officer said she suffered 70 percent burns.

She was taken to the national institute on Wednesday.
