Tas cops look into three suspicious fires

A car spotted leaving the scene of a devastating house fire east of Hobart is the focus of a police investigation into three suspicious blazes in the space of a month.

On Wednesday, a house in Gypsy Place at Primrose Sands was gutted by fire and the incident comes after destructive nearby fires of another house and a caravan.

Investigators want to speak to the occupants of a silver Subaru Forester which was seen leaving the address of the most recent fire.
