On Tuesday, NSW Police Detective Inspector Darren Newman said Mr Porter caused “significant” injuries to the couple before allegedly fleeing the scene, crashing into a tree along the way.

He got out of his car around the corner from his house and was walking towards the nearby train station when he was arrested.

He is currently assisting police with investigations and is expected to be charged with attempted murder, assault with intent to cause grievous bodily harm, driving offenses and use of weapons with intent to commit an indictable offence.

‘These people have lifelong injuries, the man in particular will need significant rehabilitation over many years after what he has been through.’
