A man whose body was found at an Essex house being used to cultivate cannabis is believed to have been from Vietnam.
Police who raided the house in South Woodham Ferrers on Tuesday are talking to the Vietnamese Embassy in London in a bid to identify the man.
Det Chief Insp Mark Hall said: "We are grateful for the assistance the local community has already given us.
"Anyone with information about activity at the site before the discovery of the body is asked to contact police."
The death is being treated as murder and a man who was arrested is currently on bail.
