Three men have been arrested on suspicion of murdering a man whose body was found more than two years ago.
Stephen Pollard, 58, was reported missing on 27 February 2015. His body was found in the Beale area of North Yorkshire on 22 May that year.
Police said at the time the death was not treated as suspicious, but new information had since come to light.
Two men from York, aged 24 and 52, and a 52-year-old man from Wakefield are in custody.
