Upon arrival, the fire service discovered that two people had been pulled from the building. “One of them was unconscious, unresponsive, and unfortunately could not be revived by NSW Ambulance paramedics,” the release stated.

NSW police assistant commissioner, Gavin Wood, called the man’s death a “tragedy,” per The Guardian.

NSW Police Assistant Commissioner Gavin Wood said early indications suggested the deceased was employed at the restaurant as a cleaner, as reported by news.com.au

“Five police officers attempted CPR on that male,” Wood said. Adding that the officers felt there was “something a little amiss in terms of the environment they were in, including an odour.”

FRNSW Superintendent Adam Dewberry added that it was “obvious to the first arriving emergency services the air quality [at the scene] was compromised.” Meanwhile, FRNSW’s Chief Superintendent Jeff Hogan said “extremely high levels” of carbon monoxide were detected at the venue.

Dewberry also noted that, “The air quality of the whole building — two levels — has been compromised, a lot of the oxygen has been pushed out.”

FRNSW stated that seven others, including five police officers and one occupant of the building, had been hospitalized. The Guardian reports that those who are in the hospital are in a “stable” condition, citing New South Wales ambulance.

FRNSW specialist hazardous materials response experts are currently investigating to try and establish the cause of the incident, but the fire service has rendered the area safe.

Restaurant owner Resham Singh told news.com.au that news of the tragedy was a “shock” to him, adding that he had only bought the business in April. “This is so sad for the family,” Mr Singh added of the deceased man, noting that his three chefs who lived above the premises escaped unharmed.

PEOPLE has reached out to New South Wales Ambulance and Resham Singh, but did not immediately receive a response.
