ONE man is dead and three people are critically ill following an apparent bungled experiment with laughing gas in a car in Sydney.
The four people, aged in their 20s and 30s, were found unconscious in a car outside a home at Toongabbie about 7.45am (AEST) yesterday.
The group had been inhaling nitrous oxide - also known as laughing gas - before falling unconscious, News Ltd newspapers reported today.
A resident, whose home backs onto Union Street where the car was found, said the man who found the group came to his house for help.
"He came over screaming that the car was full of nitrous oxide," the resident said.
"The next thing there wasa ambulance officers everywhere."
Seven ambulances were sent to the rescue after reports four people were slumped in their car seats unconscious.
One of three men, believed to live in the home where the silver Hyundai was parked, was taken to Blacktown Hospital but later died.
Neighbours described him as friendly and hard-working.
The two other men and a woman remained in a serious condition in hospital, police said.
Police have said it is too early to speculate about the circumstances of the incident.
A blue one metre-high gas tank was removed from the car for testing.
A post mortem examination was carried out on the body of the dead man yesterday.
