Footage has emerged of an argument sparking on a bus after a woman confronted two people for allegedly taking unauthorised pictures of her.
The video, shot in Sydney, Australia in April 2016, shows the filmer asking a woman to delete the unsolicited pictures she says she took of her when another bus passenger intervenes.
The man can be seen walking towards the filmer apparently threatening to "knock her out" if she doesn't stop videoing them.
"A man and woman took photos of me on their SLR camera, at a bus stop- I don't know them," the filmer wrote online.
"II saw the photos of me on their display when I subtly sat a few seats behind them and looked over their shoulder."
"When realising they had close ups of my face, multiple, I sat in front of them and started recording as I confronted them," she added.
"Since coming forward about this, 16 people I don't know have found me online to share similar stories about the same people," she said.
"Police have told us all there's nothing they can do about it as taking photos in public in Australia isn't illegal."
