3. BOB CRANE TV STAR, S SECRET SEX SHAME

Best known for his role on US TV show Hogan’s Heroes, actor Bob Crane was found bludgeoned to death in an Arizona apartment in 1978.

It’s believed the 49-year-old – who played Colonel Hogan on the hit series – was involved in an underground world of seedy sex, and was a secret sex addict who was rumoured to have had a penis enlargement.

His friend John Henry Carpenter – who’d made several shocking sex videos with Bob – was charged with the crime, but was later acquitted.
