The deceased Ranu Begum, 25, died at around 3:00am.

Sources said Ranu's husband Abdul Malik, a fish trader, and his first wife Rashida Begum poured kerosene over her and set her on fire at their house at Badda in the city at around 8:00am on Sunday.

Neighbours came to rescue Ranu after they heard her screams and rushed her to DMCH where she was admitted.

Doctors said she received 100 percent burns.

Victim's younger sister Sathi told The Daily Star that Malik lives with his first wife at Badda and Ranu lived separately in Narayanganj where she worked at a garment factory.

She alleged that Malik never took care of Ranu and did not provide any financial support.

Sathi said Malik did not disclose to Ranu about his first marriage when they first met and Malik took Tk 80,000 from Ranu at the time of their wedding two years back saying that he would invest the amount in his trade.

When Ranu came to know about his first marriage, she asked Malik to give her back the money that he took from her.

This was the main cause of their rift, she added.

Ranu came to Malik's house at Badda on Saturday afternoon for the money which led to an altercation between her and Malik.

A case was filed with Badda Police Station against Malik, Rashida, niece Nasima Akhter and nephew Swapon in this connection.
