Amy Winehouse - no drugs in her system at time of death

Toxicology tests showed there were no illegal substances in British singer Amy Winehouse's system when she died last month aged 27, her spokesman said on Tuesday.

In a statement, he added that alcohol was present, but that it could not be determined what part, if any, it played in her death.

"Toxicology results returned to the Winehouse family by authorities have confirmed that there were no illegal substances in Amy's system at the time of her death," the statement read.

"Results indicate that alcohol was present but it cannot be determined as yet if it played a role in her death."

It added that Winehouse's family were awaiting the outcome of an inquest into the "Rehab" singer's death. The inquest was opened in July and is due to resume on Oct. 26 in London.

The soul singer, famed for her beehive hairstyle and erratic behaviour on and off stage, was found dead at her home in north London on July 23.
