In pictures: Discovery of human bones in Sudbury and police raid at East Street house
Residents across Suffolk were in shock last summer after it was revealed that human remains had been discovered in one of the county's rivers.
Police were called at around 4.35pm on August 27 to reports of black bin bags containing bones having been found in the River Stour at Sudbury, near Meadow Gates and Croft Bridge.
Police tape covered the area, emergency services vehicles lined the streets, and Metropolitan Police divers took to the water to carry out searches.
The bags had been spotted by a member of the public who alerted a ranger. The ranger then opened the bags and discovered the contents.
The following day, police launched a murder inquiry and asked anyone with evidence or infomation to get in touch.
A Home Office post mortem examination carried out on August 30 failed to establish a cause of death or the identity of the victim.
It was later revealed that the remains were those of a man who was likely to have had an athletic or muscular figure. Tests also revealed he died months before the remains were found.
In the days to follow the discovery, more than 140 witnesses came forward to help officers in their investigations.
Yesterday, almost exactly eight months since the bones were first discovered, a 26-year-old man from Sudbury was arrested in connection with the incident.
Police and forensics teams descended on a property in the town's East Street, where a police spokesman said they were likely to remain into today.
Specialist dog units were also seen outside the terraced house.
The man was also arrested on suspicion of possession with intent to supply Class A drugs.
Another man was arrested at the same time on suspicion of being concerned in the supply of a controlled drug.
Detectives are now working to identify the victim through national and international databases as well as the timescale in which he died.
They are still appealing to anyone who witnessed suspicious behaviour near to the river around the time of the discovery and ask witneses or anyone with information to call 101.
