In a suspected case of honour killing, a man allegedly stabbed to death his 21-year old daughter, a day before she was to marry her betrothed.

The incident occurred on Thursday at Areekode town of the Malappuram district in Kerala.

Athira belonged to Thiyya community and was working at a dialysis centre of Manjeri Medical College, while the betrothed, who is in the Army, belonged to a backward caste. They were in a relationship for many years prior to their planned wedding.

According to police, the father of the bride was not happy with their relationship and had reluctantly given the nod for the marriage after their relatives intervened.

However, following an argument on Thursday, in a fit of rage he attacked her with a sharp weapon, police said.

She was rushed to a hospital by her relatives but was declared brought dead by doctors.

The man, Rajan (42), has been taken into custody and is being questioned, police said.
