Three escape suspicious Sydney house fire

A fire that forced a man, woman and child to flee a Sydney home may have been deliberately lit.

The 38-year-old man was treated for smoke inhalation after he, a 37-year-old woman and a seven-year-old girl escaped when they were awoken by smoke detectors at the Westmead property on Wednesday night.

Firefighters quickly extinguished the blaze, which police say may be suspicious.
