Alfie Hammett, 19, is on remand for repeatedly stabbing Ray Quigley, 18, in front of horrified shoppers in Ipswich in January last year. He had been on bail following an assault five months earlier.
EXCLUSIVE: Jurors have been told the brutal killing was the result of a deep-rooted gang rivalry between groups from Ipswich in Suffolk, where the attack took place, and Norwich in Norfolk.
