The house in Tewantin was burnt to the ground on March 29, with firefighters called to the blaze about 1.30am.
No one was home at the time of the fire, with the house’s occupants having moved out since the 13-year-old girl was allegedly beaten, stabbed and humiliated in the house on March 11.
The house’s windows and doors were then boarded up after being targeted by vigilantes in the wake of the girl’s alleged assault, which was filmed and uploaded to social media.
Police have also revealed an unknown group of people distributed offensive and harassing materials in mailboxes in the Tewantin area in the lead-up to the fire.
The CCTV footage police have released appears to show the three people putting fliers in letterboxes.

Three girls – aged 12, 13 and 14 – were charged after the girl was allegedly held against her will, punched and stabbed in an hours-long ordeal at the home.
Police have since revealed that one of the alleged offenders, the 14-year-old, has also been charged over a second alleged attack that played out on a bus six days earlier.
