A woman, 23, has revealed the horrifying moment a predator held her down and strangled her at a bus top amid a wave of sexual assaults on public transport.
CCTV shows the man listening to music on a Glen Waverly-bound train in Melbourne moments before raised his arm in a gun gesture and pretended to pull a trigger.
The man then got off at Syndal Station, where he launched the chilling random attack on a student, known as 'Susie', as she waited for her bus, reports 9News.
'He just sat on me and then when I tried to move away, he grabbed my neck and tried to strangle me,' Susie said. 'I couldn't scream at all because I was really scared.'
