Bodycam footage has captured the moment a US cop was told to 'keep his mouth shut' after gunning down unarmed Australian woman Justine Ruszczyk Damond.
Ms Damond was fatally shot outside her home she shared with her American fiancé, Don, and his son in Minneapolis in July 2017, after she called 911 earlier that evening to report a possible rape.
In the alarming clip Mohamed Noor, the officer who shot Ms Damond as she approached the police car, appears sweat-soaked and visibly anxious while a fellow officer is heard telling him to 'keep his mouth shut'.
The bodycam footage, which was tendered to the court and was released on Thursday, sees Noor pace in distress while another cop offers him some advice.
