Patna, Apr 22 (IANS): In a suspected honour killing, a woman strangled to death her daughter for having married against her wishes in Patna. The mother was arrested Sunday.

Naznin Bano alias Rani, 22, a MSc (Bio-tech) student of commerce college, was found dead at her abandoned residence located on the outskirts Badi Khagaul here Friday.

The case took a twist when Naznin's lover, Mohammad Mahfooz, Friday lodged an FIR (first information report) saying it was an honour killing.

Patna Superintendent of Police Kim Sharma said that Shamima Bano, mother of the victim, was arrested Sunday after she confessed her involvement in the murder of her daughter.

According to a police official Kamod Prasad, Naznin was first hit on the head while asleep and then strangulated.

"Prima facie, it appears that she was killed after she eloped with Mahfooz and married on April 16 against parents' wishes," said Prasad.

Mahffooz informed police that Naznin had even filed a petition before the court of additional chief judicial magistrate at Danapur on April 17, apprehending her parents might eliminate her.

Naznin and Mahffooz were studying in the same college in Khagaul, where they fell in love and decided to get married.

Police are investigating the case to ascertain role of other family members in the killing.
