A 52-year-old lawyer who was stabbed to death with a screwdriver in a busy shopping centre was a devoted father, his family has said.
Peter Duncan was attacked in what police said was an unprovoked chance “coming together” with a group of youths near Old Eldon Square in Newcastle.
He was attacked at about 18:20 BST on Wednesday and died later in hospital.
Seven teenage boys have been arrested on suspicion of his murder.
The boys, a 14 year-old, two 15-year-olds and four 17-year-olds remain in custody.
Northumbria Police said it believed Mr Duncan was attacked after a “chance encounter” outside a branch of Greggs.
Mr Duncan, from Newcastle, was described by his family as a “devoted father and husband”.
“Peter was a kind and caring man who was always first to help others,” they added.
“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 and he’ll be deeply missed by us all.”
Ch Supt Ged Noble said it appeared there had been a “coming together” at the entrance to the shopping centre, which led to Mr Duncan receiving a single puncture wound to the chest.
He added: “This was a tragic incident and our thoughts go out to Peter’s family and friends at this incredibly difficult time.
“Peter’s family have requested that their privacy is respected during this difficult time.
“We will be continuing extra patrols in the area and I would urge anyone with concerns to speak to an officer.”
