Officers from Suffolk Constabulary were contacted at 4.50pm on Saturday to reports that a 17-year-old had been stabbed in Packard Avenue.

He was taken to Ipswich Hospital for treatment where he later died.

The victim has been formally identified as Tavis Spencer-Aitkens, of Pownall Road, Ipswich.

A Home Office post-mortem examination concluded that the cause of death was as a result of a single stab wound.

Tavis had been walking back from the shops in Queen’s Way when he was approached by two males on bicycles who attacked him.

They were then joined by four to five other males who further assaulted him, before all the offenders fled the scene.

A 36-year-old woman from Essex was arrested earlier today on suspicion of assisting an offender and was questioned by detectives at Martlesham Police Investigation Centre. She has now been released under investigation whilst inquiries continue.

This came after a 41-year-old man from the Ipswich area was arrested on Saturday night on suspicion of conspiracy to murder.

Four males, who are aged 16, 18, 20 and 22 and who all have links to Ipswich, were arrested yesterday on suspicion of conspiracy to murder.

The five male suspects remain in custody after detectives made an application for a warrant of further detention at Suffolk Magistrates’ Court to allow extra time to question them. This will expire at around midnight tomorrow.

Police patrols are continuing to be stepped up in the area of the attack and across Ipswich to offer reassurance to residents.

A spokeswoman for Suffolk Constabulary said: “Officers are maintaining an ongoing dialogue with community leaders to address the concerns of people living and working in the area.”

A police pod remains in place near to the junction of Packard Avenue and King’s Way to enable members of the public to speak to police officers directly.

Officers are appealing for anyone with CCTV, dash cams, or mobile phone footage, who was in the area of Queen’s Way, Packard Avenue, Rands Way or Kingsway, between 12pm and 7.45pm on Saturday, June 2 to make contact.

Anyone with information about this crime is asked to contact the Major Investigation Team via the online portal or by calling 101 and quoting reference 30192/18.
