Seven teenagers were arrested after a man was stabbed to death in Newcastle city center.
The 52-year-old died in hospital at 6:20 pm on Wednesday after being attacked outside a Greggs bakery near Old Eldon Square.
The Northumbria police said he had been attacked with a screwdriver during a "chance encounter".
A 14-year-old, two 15-year-olds and four 17-year-olds are being held for suspected murder.
A spokesman said there was a "clash" at the entrance to the mall that caused the victim to receive a single stab wound on his chest.
He added, "Our investigations are ongoing, but we quickly arrested seven teenagers in connection with the incident who we believe are one of the prime suspects."
