Images of Rachel's dead body were used in an anti-drugs campaign

The man was one of two men held by detectives investigating the death of Ms Whitear.

Police had already released the first man without charge but it was confirmed on Friday that the second man was also free to go after he reported on police bail.

Ms Whitear, 21, who hailed from Ledbury, Herefordshire, was found dead in a flat in Exmouth in May 2000.

It was originally thought the student died of an overdose, but the case was re-opened after tests showed there was not enough of the drug in her blood to have killed her.

Wiltshire Police said the fresh investigation into her death, which was launched earlier this year, will continue.

Both men, who are from the Midlands, were arrested in August.

The Wiltshire force was chosen to head the investigation after the Devon and Cornwall Constabulary voluntarily referred the case to the PCA.

Ms Whitear's parents, Pauline and Mick Holcroft from Withington, allowed graphic images of her dead body to be used in a campaign warning of the dangers of drug abuse.
