Dorset Police has released the 28-year-old man who was arrested on suspicion of murder and supplying a controlled class A drug after a death at Bestival.
Louella Michie, 25, was found dead in woodland around 1am on Monday morning and police took the man in for questioning soon after. Police said the man knew Miss Michie and he has now been released under investigation, according to the BBC.
Dorset Police's website reads: "An initial post-mortem examination took place yesterday evening, Monday 11 September 2017, which showed no clear signs of an assault.
"However, further examinations will need to take place over the coming weeks, including toxicology, in order to establish if there are any substances in her system or other suspicious circumstances."
This year's Bestival took place from September 7 to 10 at Lulworth Estate in Dorset.
