Michael Gilbert was identified through his fingerprints
Two men have been arrested on suspicion of the murder of a 26-year-old man whose decapitated body was found in a Bedfordshire lake.
The men, aged 22 and 24, are both from the Luton area and are being questioned at the town's police station.
The body of Michael Gilbert was found at the Blue Lagoon in Arlesey on Sunday, wrapped in layers of packaging.
Mr Gilbert, who had been living in Blackburn, Lancashire, was identified through his fingerprints, police said.
Police are trying to piece together how and where he died and urged anyone with information to come forward.
Officers said Mr Gilbert also had links to Cambridge and Kings Lynn in Norfolk.
Det Ch Insp Jon Humphries said: "While we have made these arrests I would stress that this is still a 'live' investigation and we are still actively seeking people with information about Michael's death to contact us.
"I would also urge anyone who may have seen Michael in recent weeks to contact us so that we can start to piece together the last few days of his life."
A wheelbarrow was also found at the scene which police believe may have been used to move the body to the lake.
The cause of Mr Gilbert's death has still not been established and a further post-mortem examination will be carried out to further assess his injuries, he said.
