Police have been filmed arresting a young boy while telling him to "shut up" in Victoria.
The video, which was uploaded to Facebook, appears to show at least three officers pinning the 12-year-old boy to the ground at Bendigo Railway Station on Friday.
With his face pressed against the concrete, the boy, who police believed at the time to have autism, is held down by the officers.
"He's got autism so he doesn't understand," one officer can be heard saying.
