THE 32-year-old whose decomposing body was found dumped in a Warlingham well had been "severely beaten".
The remains of Damian Chlywka were discovered wrapped in tarpaulin at the bottom of a well at a house in Audley Drive by a gardener last November.
Police launched a murder investigation, identifying the body a fortnight later.
They determined that Mr Chlywka had come to the UK in 2008 and that his body had been in the well for about two years.
Last Wednesday officers appeared on BBC One's Crimewatch programme to issue a fresh appeal for information.
While it was already known Mr Chlywka had suffered injuries consistent with an assault, the appeal said he had been "severely beaten, and had many broken bones".
Acting Detective Chief Inspector Michael Norman said on the show: "Mr Chlywka had sustained fractures to his ribs and eye sockets.
"From the post mortem we discovered that the body appeared to have been bound by the wrists by tape. He had been severely beaten, and had many broken bones."
An unregistered Oyster Card found on him had last been used on April 27, 2011 – which corresponds with his last known sighting.
The programme also revealed more details about Mr Chlywka's background. He was born in Glogow, in south west Poland. Police believe he came to the UK in response to a job advert.
He worked consistently for a number of businesses in Croydon and Surrey, including car valeting and as a builder, until his disappearance.
The house where his body was discovered had been used as accommodation for Polish workers since 2006. More than 80 Polish males have lived there since, and a large number of other Polish males have used the house as a drinking venue.
Nine people arrested in connection with Mr Chlywka's death are currently on bail while the investigation continues.
Anyone with information on the case should call police on 101.
