Murder detectives believe information could yet come to light in the investigation into the death of Ipswich teenager Tavis Spencer-Aitkens.

Almost two months since the 17-year-old was fatally stabbed in Packard Avenue on June 2, the town’s police commander has stressed the investigation remains open for evidence.

Three men and a teenage boy have been charged with murder, while two men remain on bail after their arrests on suspicion of conspiracy to murder.

Superintendent Kerry Cutler said: “We want to ensure that justice is done for Tavis, his family and the wider community.

“I don’t want anyone to think information is no longer relevant.

“I’m keen to hear from anyone who may have been reluctant to come forward – or may have since overheard something.

“We understand some may feel concerned about speaking directly to the police – but they can contact Crimestoppers anonymously.”

In the days and weeks following the tragedy, members of the community called for action against violent crime.

Local leaders faced criticism over the lack of opportunities for younger people in the area of Nacton Road during a public meeting in the wake of the killing.

Superintendent Cutler said: “People have a right to feel angry and want an explanation because they not only lost a member of their community, but a child.

“It’s a sign of how much people cared about Tavis and the need for change – not just in the Nacton Road area, but across Ipswich.

“Our safer neighbourhood team is regularly visiting the community and our officers will continue to police the area as they have – but there has also been a lot of long-term activity for the last year to support young people in making better choices.

I think some of the long-term solutions sit around education and ensuring they have the right opportunities; that we don’t marginalise people, and that we have diversions in place at the earliest opportunity.

“When dealing with young people and gangs, we’re constantly thinking about referrals with our partner agencies. It’s something we’ve always done.”
