DETECTIVES have closed the investigation into an attack at Ulley Country Park.
Det Insp Mark Monteiro said the victim, Adrian Kozak (37), had told police he did not want to assist them with identifying who was responsible for attacking him.
Mr Kozak, a Polish national, was found with life-threatening injuries at an angling peg at Ulley Reservoir by a dog walker at around 8.35am on Monday, October 16.
Det Insp Monteiro said: “It does appear that this was a group of individuals who have been drinking at the site and an altercation has got out of hand.
“It was not an unprovoked attack and we want to make that pretty clear.”
The detective added that two men, arrested in connection with the incident, had been released without charge.
