A man arrested on suspicion of murder following the stabbing of Ipswich teenager Tavis Spencer-Aitkens has been released from police custody.

The 17-year-old was attacked by a group of males around 4.50pm on Saturday, June 2, in Packard Avenue, during which he suffered a fatal stab wound.

Yesterday, officers arrested a 28-year-old man from Ipswich on suspicion of murder and he was questioned by detectives before being released under investigation pending further enquiries.

Officers also searched three addresses in the Chantry area of Ipswich yesterday.

Police said these were conducted both in connection with the arrest and also as part of ongoing proactive work across the town to combat the supply of illegal drugs into Suffolk.

As a result of these searches, a quantity of cannabis was discovered and seized.

Six people have previously been charged with murder in connection with the death of Tavis Spencer-Aitkens as follows:

- Aristote Yenge, 23, of Ipswich, and a 16-year-old boy from Colchester (who cannot be named for legal reasons), were charged in early June.

- Callum Plaats, 23 of Ipswich, and Adebayo Amusa, aged 20, of Barking in east London, were both charged in late July.

- Leon Glasgow, 42, of no fixed abode, and Isaac Calver, aged 18, of Ipswich, were both charged at the end of August.

All six are currently remanded in custody pending next appearances at Ipswich Crown Court on Friday, September 21.

A 20-year-old man, arrested on suspicion of conspiracy to murder, remains on bail with the authority of the magistrates’ court until Tuesday, December 4.
