A man has been arrested after the discovery of human bones in black bin bags were dumped in a river last summer.
The black bin bags were hauled out of the water by a nature reserve warden who alerted police at around 4.35pm on August 27, 2020.
After nine months of extensive inquiries officers arrested a 26-year-old man from Sudbury on Tuesday.
He was also arrested on suspicion of possession with intent to supply Class A drugs.
He has been taken to Bury St Edmunds Police Investigation Centre where he will be questioned by detectives.
A Home Office post-mortem examination was not able to establish a cause of death or the identity of the dead man.
Forensics tests have established that the victim was an adult male, who was likely to have been of an athletic or muscular build.
A small amount of additional human remains were found as a result of searches of the river, with DNA testing of these remains confirming that they are from the same person as the original discovery.
A second man was arrested at the same time on suspicion of being concerned in the supply of a controlled drug. He has not been arrested in connection with the discovery of the human remains.
Officers are also currently searching a property in Sudbury following these arrests and this work is expected to continue into tomorrow.
A Sudbury Constabulary spokesman said: “Detectives continue to appeal for anyone who witnessed any suspicious behaviour near to the river in the week preceding the discovery to come forward.
“They would also like to hear from anyone who has seen black bin bags in unusual locations, such as ditches or hedgerows.”
