A new inquest could be held into the death of a heroin addict whose dead body was pictured in an anti-drug campaign.

Rachel Whitear, from Ledbury, Herefordshire, was discovered holding a needle in a room in Exmouth, Devon, in May 2000, after an apparent overdose.

An inquest recorded an open verdict and the circumstances of the 21-year-old's death have remained unclear.

Wiltshire Police have won the backing of the Attorney General to ask the High Court for a new inquest.

The move follows the discovery of new information about the death of Ms Whitear amid continuing speculation that she may have been murdered.

At the original inquest, coroner Richard Van Oppen said he was certain Ms Whitear did not die of a drug overdose and recorded an open verdict.

No post-mortem examination had been held by Devon and Cornwall Police.

Tests revealed that there had not been enough heroin in the syringe in Ms Whitear's arm to have killed her.

The concerns led to the exhumation of Ms Whitear's body in March 2004 and Wiltshire Police were brought in to carry out a fresh inquiry.

A full report into her death was submitted last year to Dr Elizabeth Ear-land, coroner for Exeter and Greater Devon, but she decided there were no grounds for a fresh inquest.

Ms Whitear's parents, Mick and Pauline Holcroft, said at the time they were "extremely disappointed and perplexed" at the decision.

Wiltshire Police said in a statement: "Following an application by Wiltshire Police, the Attorney General gave authority for an application to the High Court asking for the original verdict to be quashed and a new inquest opened."
