Police investigating a suspicious fire at a Gulliver property on Boxing Day, December 26 have released new footage, which they hope will help them find those responsible for starting the blaze.
The security camera vision shows a male riding his bike along Mooney Street, at 2:40am on December 26.
Additional footage shows another person, possibly female, walking along Tippet Street from Mooney Street and a person on an e-scooter riding along Tippet Street towards Mooney Street, just before 3am.
Police believe the fire which destroyed the Mooney Street property started shortly after 3am.
Detective Inspector Damien Smith said, while these people are not considered suspects, police believe they may be able to help.
"These people may have seen something which could assist us with our investigation.
"We would encourage them to contact police,' he said.
Police have also released body camera footage showing an officer rescuing a woman from inside the house.
The police officer sustained minor burns to his hands, while the 53-year-old woman remains in a critical condition at the Royal Brisbane Hospital.
An 83-year-old man was critically injured and is being treated at the Townsville Hospital.
A 55-year-old man sustained non-life-threatening injuries and has been released from hospital.
The family's five pets also went missing after the fire - two dogs have since been found and are receiving treatment.
Two cats and two dogs, remain missing.
Detective Inspector Smith said the veracity of the fire has made it very difficult to determine where and how it started.
"We do believe the fire may have started outside near the premises and some sort of accelerant has caused the fire to spread throughout the house.
"The property has been completely destroyed," he said.
Detectives investigating the arson are appealing for public help and are urging anyone with any information to come forward.
"A family has lost everything and two people are fighting for their lives.
"Someone knows something, it doesn't matter how insignificant the information may seem, every piece helps us get closer to finding out what has happened," Detective Smith said.
