Mr Duncan's family said in a statement: 'Peter was a kind and caring man who was always first to help others.
'He was a devoted father, husband, son, brother, uncle and friend and loved by all who knew him. His death will leave such a huge hole in our lives.'Utter scum waste of oxygen perps:
Stephen Humphries, 34, a waiter, added: 'There was a group of people around the guy on the floor, clutching his chest. There was a group of young lads running around shouting, they did not seem too bothered.
'The young lads were swearing and saying 'he was going to get it' and 'it was coming to him'.'Ineffective revolving door criminal justice system:
Chief Superintendent Ged Noble said the inquiry into Mr Duncan's death is at an early stage but said it appears he was attacked at the entrance to the shopping centre.
He added: 'We have very quickly made seven arrests. The persons involved are known to us.'This latest murder is a microcosm of modern UK life, isn't it?
