A man was beaten to death after a Motorhead gig in Leeds and West Yorkshire Police are appealing for witnesses.
Andrew Crawford was attacked on Dudley Way last Thursday (November 25). He suffered serious head injuries and was taken to Leeds General Infirmary, where he died.
The attack followed an incident at the O2 Academy where two men set his friend's hair on fire, reports BBC News.
Two men were later arrested, but have been released on bail pending further inquiries.
