Crump-Raiswell Kieran, 18, was heading to look for a job when Imran Hussain, 27, walked up to him and without warning stabbed him four times in the chest.

Manchester Evening News (h/t Susan K) Witnesses to the shocking scene in Whalley Range said Hussain appeared to be “sniggering” as he ran to his car and drove off, jurors heard. The killing was the second of two street assaults committed on total strangers within 12 days in January.

Hussain, from Bracknell, Berkshire, drove from his student flat in Coventry on January 4 and punched a man in the face in Nottingham and ran off.

Peter Wright QC, prosecuting, said: “It is the prosecution case that on this occasion, fortified by the apparent ease at which a stranger could be attacked, this time he travelled to Manchester armed with a knife and intending to kill someone.”
