Seven men have been arrested in England on suspicion of murder after a body was found in a well.
The discovery was made by two gardeners at a house in Warlingham, Surrey, on Friday afternoon. The body is still in the well.
"We need a police diving team ... and we need to recover the body intact to preserve forensic evidence,'' said Detective Chief Inspector Cliff Lyons on Saturday. ''The process of recovery is likely to take some time.
"It is a murder investigation. As far as I am concerned, when a body is found in a well it either fell in there or was placed in there, and the evidence is apparent that the body was placed in there.
