Wac solutions has partnered with Assured Security to provide access to the video footage from the 2014 incident in which the Sydney siege gunman Man Haron Monis shot and killed 22-year-old Australian national Rachel Broom.
In June, Ms Broom was shot at point-blank range in the Sydney suburb of Manuka.
Assured Security was able to identify the gunman, Monis, and was able then to obtain video footage.
The video footage, taken by a bystander, was sent to the ABC for analysis.
It shows Monis shooting Ms Broooms dead, and Ms Brooom being dragged through the street by two police officers before being taken into custody by police.
Ms Broom’s father, Anthony, was later able to speak to the public for the first time since the shooting.
Mr Monis has been charged with killing Ms Brooms father, and the inquest into her death is yet to begin.
This is the second time Wac has partnered Assured to help secure the video evidence for law enforcement agencies.
After the shooting, Assured secured footage from a different incident that occurred in February.
A Sydney man was charged with assaulting an officer at a cafe in Sydney’s west, after he attacked two police.
