Police said that Irfan attacked Rizwana when she, accompanied by her 12-year-old niece, was on her way to her elder sister''s house near Balakund in Dadabari.
Irfan came from a nearby shop and stabbed his wife with a knife multiple times before fleeing from the spot, Deputy Superintendent of Police, Dadabari police station, Ankit Jain, told reporters.

Anita, has also claimed that Irfan had lured her sister into marrying him against their parents'' will.
The victim was the ninth among 10 sisters, and was 17 years old when she left her home to marry Irfan, Anita said.
She claimed that after their marriage, Irfan would often harass Rizwana for money, which she would procure from her sisters.
Anita said Rizwana had forgiven her husband for his attempt to sell her in Goa and again started living with him, but over two months ago, Irfan thrashed her and she sustained injuries to her head, which required 17 stitches.
On Thursday, four of Rizwana''s sisters demanded capital punishment for Irfan. PTI CORR VN VN ANB
