Ten men have been arrested on suspicion of murder after the body of a man was discovered in a garden in Chelmsford.
Essex Police were alerted to the incident by the Ambulance service just after midnight.
A 39-year-old man was found in the rear garden of a house on the A414, London Road, in Chelmsford, opposite Hylands Park where the V Festival is being held.
His next of kin have been informed of his death.
The 10 men who have been arrested will be interviewed by police.
Detectives from the Kent and Essex Serious Crime Directorate need to speak to everyone who attended, what police believe, was a private party at the property during the late hours of Saturday and the early hours of this morning.
Anyone with any information is asked to urgently contact Essex Police on 101 and leave their contact details.
