The Age’s South-East Asia correspondent Lindsay Murdoch said the attack happened in Patong, a tourist hot spot notorious for late-night assaults and petty crime.

‘We know initially the police knew nothing about it,’ he said.

‘It was posted on Facebook by somebody who was there who worked for a nearby bar (and it) went viral because it’s quite a shocking video, the brutality is shocking.’
