Detectives investigating the death of a man whose body was found in entertainer Michael Barrymore's pool say they have new information about the case after a renewed appeal last week.
Stuart Lubbock, 31, was found dead at Barrymore's home in Roydon, Essex, on 31 March 2001, having suffered serious sexual injuries.
Police offered a £20,000 reward for information leading to a conviction.
They are now following up several calls, as the
Mirror reported.
As they
relaunched the appeal, Det Ch Insp Stephen Jennings said: "I believe that [Stuart] was raped and murdered that night.
"One or more of those party-goers are responsible for that serious sexual assault on Stuart Lubbock."
The new senior investigating officer said three people previously arrested, including Barrymore, had not been "completely eliminated".
