A 55-year-old man arrested in connection with the death of a woman at an Ipswich flat has been released without charge.
A murder probe was launched as police were called by the ambulance service to a flat in Foundry Lane just before 3.30am on Thursday after a woman in her 60s was found dead.
Forensics teams were seen attending the scene after police revealed the death was being treated as suspicious.

However, a Home Office post-mortem examination was completed on Thursday evening and the initial conclusions were that the woman died from natural causes.
Police are no longer treating the death as suspicious.
Suffolk police confirmed the man has been released from police custody and will face no further action.
