Levin police are seeking information about a distinctive blue petrol container used to light a fire at a Levin house early Monday morning.
It is the second fire at the Stuckey St property in the past two weeks and police said it was only good luck no-one has been injured or killed.
The alarm was raised at about 4.30am on Monday and firefighters called to the property found the front corner of the home alight. Firefighters doused the flames, but not before a front wall was damaged.
It appeared someone had started the fire beneath the corner of the property and a blue petrol can had been ignited and left at the scene.
Senior Sergeant Sarn Paroli said nobody was home when the fire was noticed. CIB staff are investigating.
