A man whose bound body was found in a well in Surrey has been identified.
A team of specialist officers, including Metropolitan Police divers, retrieved Chlywka's trussed-up body from the well. It showed signs of injuries "consistent with an assault".
The body is thought to have been in the well for around two years.
A 41-year-old man and a 33-year-old man were arrested on suspicion of murder on Friday and have since been bailed pending further investigations.
A post-mortem examination on 17 November did not provide a cause of death, and further tests are being conducted.
Detective Chief Inspector Cliff Lyons, who is leading the investigation, said: "Damian had lived at various addresses across London, including two known to be in the Croydon area. At one point he had lived at 11A Audley Drive.
"Our focus now is to build up a fuller picture of Damian's life in the UK.
"We have given the difficult and heartbreaking news to his family who are distraught that this has happened to their loved one.
"I am appealing to anyone who knew or previously worked with him to contact the police and help us to piece together a picture of Damian's life and how it came to end in these distressing circumstances."
Any witnesses or anyone with any information is asked to call the incident room on 020 8721 4961 or call Crimestoppers anonymously on 0800 555 111.
Seven men, aged between 21 and 27, were initially arrested on suspicion of murder and were later released on bail until December.
