Staff at Sir Charles Gairdner Hospital attempted to calm him down

The man, high on meth, had no idea his friend, 44, was already dead

Drug-affected man took his dead friend to a Perth hospital last month

A man who had been dead for over a day was taken to the emergency department of a Perth hospital by his friend, who was 'high on meth' at the time.

The drug-affected man drove his truck up to the main entrance of Sir Charles Gairdner Hospital on July 8, completely unaware of his friend's deceased state.

Witnesses told Perth Now that hospital staff attempted to keep the tragic news from the intoxicated man, who was already acting agitated and confused.

Patients waiting for treatment in the emergency department were subjected to some delays, with only 'priority one' ambulance and walk-in cases receiving attention.

Western Australia police said that the death of the 44-year-old man, from Cannington in Perth, was 'sudden' and 'non-suspicious'.

They confirmed they had cordoned off the area to investigate.

A spokesperson from the hospital told Perth Now that they had been forced to create alternative entry and exit points as a result of the incident.

However, the incident reportedly had minimal impact on the ED and was 'largely business as usual' insisted the spokesperson.

The man, who witnesses claim was high on methamphetamine (known as ice in Australia), was in an agitated state when he arrived at the emergency department

It comes amidst reports that a man posing as a doctor snuck into restricted areas of the public hospital this year - wandering through different wards, hanging out int he doctor's lounge and checking patient's charts.

Staff at Sir Charles Gairdner Hospital in Perth became suspicious after seeing the man repeatedly visiting the hospital and using areas restricted to hospital employees, according to the West Australian.

Security guards questioned the man after being alerted by staff and he has not been seen at the hospital since, but the incident has called into question the hospital's security risk.
