Man dead after smoke forces evacuation at Guildford, Sydney

A man has died after unattended cooking filled his unit with smoke in western Sydney, forcing him and another person to evacuate.

The incident happened in the early hours of Sunday in the suburb of Guildford.

A police spokeswoman said the man who died was believed to be in his 60s.

The alarm was raised about 3.45am on Sunday, with firefighters rushing to the block of units on Calliope Street.

A Fire and Rescue NSW spokesman said two people had evacuated the unit themselves.

One of the people became seriously sick and died at the scene despite medical intervention.

The unit was not on fire but was filled with smoke, the spokesman said.

He said food catching fire was a common occurrence seen by firefighters.

Further details of the cooking appliance used have not been confirmed by authorities.
