A body found in east London parkland has been identified as banker Neil Coulbeck, sources have told the BBC. The banker worked for the Royal Bank of Scotland, and had been questioned by the FBI about the Enron fraud case. Police were keeping an open mind about whether the death was linked to the Enron investigation, which involved RBS subsidiary Natwest. Three British former Natwest employees are being extradited to the US on Thursday to face fraud charges. Police were called to the park near Newgate Street in Chingford after the body was discovered by a member of the public on Tuesday. A police spokesman said the man's body was on the ground when it was discovered. They said the death was being treated as unexplained. He added officers from the Homicide and Serious Crime Command were investigating because of their resources and expertise.
