Police admit that an inquest report detailing Amy Winehouse’s death was “sent to wrong address.”

The report, believed to contain information relating to how Winehouse died, was supposed to be delivered to the singer’s family.

Instead the report was handed in at a North London police station last Friday.

A Scotland Yard spokesman said on Monday: “Police were informed on October 21st that material relating to a forthcoming inquest may have been delivered to an incorrect address.

“That Friday evening that material was handed in at a police station in North London. Inquiries are now under way to establish the full circumstances of this matter.”

How and where report was sent is still unknown.

The spokesman declined to comment on whether the inquest report was sent to a newspaper.

Winehouse, 27, was found dead in her North London home on 23 July, after struggling with alcohol and drugs.

Since Winehouse’s death her album Back to Black has become Britain’s bestselling album of the 21st century.

Following her troubled death, Winehouse’s family have launched The Amy Winehouse Foundation for vulnerable young people.

Started in September, the foundation aims to support “charitable activities in both the UK and abroad that provide help, support or care for young people, especially those who are in need by reason of ill health, disability, financial disadvantage or addiction.”

An inquest into the singer’s death was opened and adjourned on 25 July, two days after she was found dead. The inquest is expected to reopen this Wednesday.

An initial postmortem examination following Winehouse’s death proved inconclusive. The Winehouse family later said toxicology reports confirmed the absence of drugs in her system at the time of her death.
