Police in Northland are seeking information on a vehicle believed to be connected to a fire in Whangārei earlier this week.
Emergency services were called to the fire at an address on Raumanga Valley Road in Raumanga at around 6.20am on Wednesday.
Police said all five occupants were asleep when a couch on the front deck was “deliberately” set alight.
They were evacuated safely, and no injuries were reported.
Sergeant Shane Pilmer said witnesses described seeing a white or silver-coloured vehicle around the time of the fire.
“We are interested in hearing from anyone who may have seen this white or silver-coloured car around Raumanga Valley Road or Mahana Place, between 5.45am and 6.15am on Wednesday.”
Police said investigators still wanted to hear from anyone who might have seen suspicious activity before or after the fire, including anyone with dashcam footage.
Anyone with relevant information is encouraged to contact police via 105.
