A LITTER of puppies died in a house fire in Sydney’s south west, believed to have been caused by an electrical fault from an alleged cannabis hydroponic set up.

A fire broke out at a house on Araluen Ave, Moorebank about 7.20pm last night and when emergency crews arrived, it was well alight.

The resident of the house was arrested after firefighters brought the fire under control and allegedly found three rooms were being used for the cultivation of cannabis.

It is understood the man and his partner, who is pregnant, lived at the house with their two young children and are not believed to be insured.

One neighbour said he tried to fight the fire with a hose but the water pressure on the street was horrendous so it was no use.

About 8pm firefighters gave a small bag of clothes to Mr Parnell, one of the only things they could save.
