A man arrested on suspicion of the murder and indecent assault of Stuart Lubbock at the home of Michael Barrymore 20 years ago has been released under investigation by police.
The 50-year-old suspect, who has not been named, was arrested in Cheshire on March 17 after 'significant new information' came to light, Essex Police said.
He was subsequently released on bail until April 12, and the force said he has since been released under investigation.
An Essex Police spokesman said: 'A 50-year-old man arrested on suspicion of the indecent assault and murder of Stuart Lubbock has been released under investigation while our enquiries continue.'
Barrymore, was arrested as part of the investigation in 2007 before being released without charge, later launched a high court case for £2.4million damages for wrongful arrest. He received a nominal sum after Essex Police won an appeal
Butcher Mr Lubbock, 31, had been attending a party at Barrymore's luxury home in Roydon with eight other people on March 31 2001 when he died.
A post-mortem examination showed Mr Lubbock had suffered severe internal injuries which suggested he had been sexually assaulted.
Alcohol, ecstasy and cocaine were found in his bloodstream.
The coroner recorded an open verdict.

Stuart Lubbock's death shocked Britain and ended Michael Barrymore's TV career overnight. The star, who made millions as one of the UK's top TV personalities of the 1980s and 1990s, has always denied playing any part in his suspected murder.
He has been reduced to playing Strike It Lucky live with fans on Instagram and was last seen on TV during a stint on Celebrity Big Brother in 2006.
A planned appearance on Dancing on Ice last year never happened after he broke his wrist and he was never invited back.
Last year's Channel 4 documentary about the case prompted Barrymore, 68, to issue a fresh denial of any wrongdoing, saying: 'I have had nothing to do with this whatsoever and yet I keep getting bashed and bullied by the media.'
Mr Lubbock, 31, had been attending a party at Barrymore's luxury home in the Essex village of Roydon with eight other people on March 31, 2001.
Stuart was found floating in Mr Barrymore's swimming pool but nobody has been brought to justice for causing his death.
Detectives believe that Mr Lubbuck may also have been abused by a pool thermometer and outhouse handle that went missing after his suspected murder.
The initial investigation was deeply flawed after officers failed to secure the crime scene and assumed Stuart had drowned.
