Photographs of three men wanted in connection with the murder of a man at a cannabis factory in South Woodham Ferrers, Essex have been released. [26 July 2011]

Detectives launched a murder investigation after the discovery of a Vietnamese man’s body in an industrial unit in Redhills Road on 9 December 2010.

A post-mortem examination showed that the 39-year-old man, named as Duy Hai Tran, died as a result of a broken spine and fracturing of the skull.  

Police believe he died after falling through a skylight in the roof during a break in at the cannabis factory.

Detectives are now appealing for the public’s help to trace three men who are also wanted for questioning in connection with the murder and burglary.
