To what extent was the murder of Glasgow shopkeeper Asad Shah inspired by the killing of a politician in Pakistan five years ago? And what does this mean for the UK?
CCTV images of the moments just before the murder of Glasgow shopkeeper Asad Shah show his killer, Tanveer Ahmed, angrily remonstrating with him.
Ahmed was incensed by YouTube videos Shah had made in which he claimed to be a prophet. Ahmed saw this as blasphemy that needed to be punished. He travelled to Scotland from his home in Bradford, then stabbed and beat his victim to death.
Ahmed was sentenced to a minimum of 27 years in jail – but appears completely unrepentant.
