Two teens have been arrested following the fatal stabbing 18-year-old Raymond James Quigley in Ipswich town centre earlier this year.
On Tuesday, police arrested an 18-year-old man from Norwich and a 16-year-old from the Fenland area of Cambridgeshire on suspicion of murder.
Both were taken into police custody for questioning and have been released on bail until September, pending further enquiries.
Two teenagers, Alfie Hammett, 18 and from Larkhill Rise in Rushmere St Andrew, and Joshua Howell, 18 and from Wellington Street in Ipswich, were subsequently charged in the aftermath of the attack, which happened on Tuesday, January 17.
They have both denied murder and possession of an offensive weapon and remain on remand in youth detention awaiting their trial, which is due to commence on Monday, December 11.
Mr Quigley, known as James, was fatally stabbed in Westgate Street, Ipswich.
He was approached by two men and attacked at about 3.35pm.
Whilst police units and ambulance crews services were in attendance, and despite the efforts of the medical personnel, Mr Quigley died at the scene.
A second man, who was with the victim, was then chased by one of the suspects and threatened with a knife, but escaped unharmed. The suspects then made off in different directions.
A Home Office post-mortem examination concluded that Mr Quigley sustained four stab wounds to his torso and died as a result of his injuries.
In a tribute shared after his death, Mr Quigley's family said: “To say that we are devastated is an understatement.
