Then came the deliberately lit fire that all but destroyed an unoccupied house in Matthews Road on October 2, set alight in broad daylight like the Cobden Street house.
Police extremely concernedDetective Sergeant Theo Akroyd said police were extremely concerned about these fires.
“We are still trying to establish if there are any links between them," he said. “It is possible it is the work of one person but we have no evidence to suggest that at this stage. Whatever the situation, because of the nature of these fires, they pose a serious risk to life and property.
“We would ask the community to be extra alert to suspicious behaviour in their neighbourhoods.”
Witnesses from the Matthews Road fire and the Cobden Street fire on Tuesday have reported seeing a male riding off on a bicycle immediately after the fires started.
“The description we have from Tuesday’s fire is of a male Maori or Polynesian, a dark-skinned person, of medium build, who was wearing a hoodie.”
Specialist fire investigator Derek Goodwin said the fire service was likewise becoming increasingly concerned about the situation.
“Someone could get injured or worse if the spate of fires keeps happening. We would urge people to support the police in their inquiry to catch whoever is doing this.
“If people see suspicious activity in their neighbourhood they should communicate with the police immediately.”
Mr Goodwin said given the concerns it was also a good idea for people to ensure smoke alarms in their homes were operating effectively.
“They should also be sure of their escape routes from their homes should a fire occur.”
