The first arrest has been made in the hunt for those allegedly responsible for riots which broke out in the aftermath of the Sydney church stabbing.
Dramatic vision of a raid by heavily armed tactical officers showed the moment cops slapped cuffs on a 19-year-old man in Doonside, in Sydney's west.
Police Commissioner Karen Webb on Tuesday warned alleged rioters who 'turned on police' that they can expect a 'knock at the door'.
'It might not be today, it might not be tomorrow, but we'll find you and we'll come and arrest you.' she said.
