The Svea Court of Appeal confirmed the sentence passed to Subhi Othman by Nyköping district court in March.

62-year-old Othman had admitted to killing his daughter in November 2010.

Othman stabbed his daughter on the stairs of the family home in Katrineholm after which he gave himself up to the police.

In interviews he explained that he had killed her as he considered her lifestyle to be “indecent” and that he was faced with no other alternative in order to protect the family honour.

When police arrived on the scene, they found his daughter lying in the foetal position at the bottom of the stairs. She had been stabbed 53 times.

According to a report in the Aftonbladet daily, Othman began hating his daughter after her husband had filed for divorce. Behind the divorce petition was a rumour of infidelity.

The 21-year-old woman and her three-year-old daughter had moved from Gothenburg to Katrineholm, in central Sweden, to live with her parents following the divorce.

The district court found that the murder had been premeditated and especially brutal.

The man will be extradited from Sweden as soon as he has served his sentence.
