Police have released a composite image of a man as part of their investigation into a fatal fire in Sunshine North in February of this year.
Following an appeal for public information on Friday of last week, investigators are releasing additional CCTV of the white dual cab ute which was seen in the Melton area immediately before and after the incident occurred on Friday, February 23.
They are also releasing as a composite image of a man seen in the vicinity of the car fire.
Emergency services were called to reports of a panel shop on fire on Bunnett Street just after 4am on Friday, February 23.
Investigators have been told a white dual cab ute pulled up outside the business at 3.51am, before a male exits the vehicle, emptying the contents of a jerry can on the factory door before igniting it.
He returns to the waiting vehicle as the building goes up in flames, and they flee the scene.
The fire subsequently spread to a building behind the panel shop, a factory on Marshall Street, where two people were sleeping inside at the time.
The two men, a 42-year-old and a 48-year-old both from Sunshine North, died at the scene.
Detectives believe the initial fire was a targeted attack have released CCTV of the vehicle involved in the hope someone may recognise it.
The white dual cab ute has a silver tray and is captured on CCTV travelling on Bunnett Street in a northerly direction.
The additional CCTV released today captures the ute on Albert Drive in Melton South about 4.40 am on February 23.
It was later found burnt out on Gisborne Road in Coimadai about 5.20am.
Investigators are urging anyone who recognises the vehicle or who may have been in the area the time and has CCTV or dashcam footage to contact police.
