Carrie Fisher had traces of cocaine, heroin and party drug MDMA, also known as ecstasy, in her system when she died suddenly in December, according to a full autopsy report released on Monday.

The autopsy report from the Los Angeles County Medical Examiner could not ascertain what effect the cocaine and other drugs may have had on her system.

Coroner's officials ruled on Friday that the death of the actress was due to sleep apnea and other causes.

Ms Fisher died aged 60 on 27 December 2016, four days after she went into cardiac arrest on a flight from London to Los Angeles.
