Six bailed over James Attfield Colchester murder inquiry
Six people arrested over the murder of a man found stabbed 102 times in an Essex park have been bailed.
James Attfield, 33, was found dead in Castle Park off Guildford Road, Colchester, on 29 March.
Three women and three men were arrested on Thursday at properties in Colchester, Ipswich and Southend and released on bail until September.
In April, a reward of up to £5,000 was offered to find the killers of Mr Attfield.
Essex Police have said his death was being investigated "in parallel" with the killing of a Saudi Arabian student Nahid Almanea, who was found stabbed 16 times in June, also in Colchester.
