An attractive 16-year-old Muslim teenager was stabbed to death 23 times by her elder brother “to protect the family’s honour” after he tricked her in to meeting him at a McDonald’s burger bar car park.

Ahmad was said to be ashamed of his sister for wearing “inappropriate” clothing, although he himself has a history of criminal behaviour.

Judge Wolfgang Backen read out his list of previous crimes: theft, several cases of actual and grievous bodily harm, stabbing a man and drink-driving.
