A photo of Duane Denny, whose body was found dumped in London weeks after he went missing in Reading, has been released by police appealing for information.
A 47-year-old has been arrested on suspicion of murder and remanded in custody while on Saturday a woman, aged 48, was also arrested on suspicion of assisting an offender.
The woman has been released on bail until October 14.
