A massive manhunt is under way in England for a lone knifeman who went on a 90-minute rampage in Birmingham city centre overnight, killing a man and injuring seven other people.

West Midlands Police declared a major incident after being called to reports of a stabbing just after midnight on Sunday, before more calls came in of further attacks.
