Damian Chlywka's body is believed to have
been in the well for two years
A man whose bound body was found in a well in south London has been identified by police.
Damian Chlywka, a Polish national born in 1981, is believed to have been in the well in Audley Drive, Warlingham, for two years.
Two men, aged 41 and 33, were arrested on suspicion of his murder on Friday.
Seven men, aged between 21 and 27, who were previously arrested on suspicion of murder, remain on police bail.
Det Ch Insp Cliff Lyons, of the Metropolitan Police, 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 Road. 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."
Mr Chlywka's body was found by workmen on 15 November. Police said his body had suffered injuries consistent with an assault, prior to being placed in the well.
A post-mortem examination did not provide a cause of death and further tests are being carried out.
