A man has been found dead at a house near the site of a major pop festival.
Essex Police said officers were called by the ambulance service just after midnight when a 39-year-old man was found in the rear garden of a house on London Road, Chelmsford, opposite Hylands Park, where the V Festival is taking place.
Ten men have been arrested on suspicion of murder.
A spokesman said: "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/early hours of this morning."
Anyone with any information is asked to contact Essex Police urgently on 101 and leave their contact details.
