The daughter of Holby City actor John Michie apparently took an "illegal substance" before her death at Bestival, her family has said.
Louella Eve Fletcher-Michie, 25, was found dead in a wooded area on the edge of the festival site at Lulworth Castle, Dorset, on Monday.
Dorset Police arrested musician Ceon Broughton, 28, who was known to Ms Michie, on suspicion of her murder and supplying a class A drug.
Mr Broughton, from London, was released under investigation on Tuesday after a post-mortem examination showed no clear signs of assault.
Police said further tests, including a toxicology report, will take place over coming weeks to establish if there were any substances in Ms Michie's system or other suspicious circumstances.
