Wild moment man is knocked out in broad daylight in Sydney’s west

Watch the shocking moment a man is knocked unconscious by a king hit in broad daylight on a Greenacre street.

Shocking video has emerged of a king hit attack in broad daylight on a busy Western Sydney street.

It is understood the incident occurred in March this year outside the One-Stop Bait n Tackle store, on the corner of Banksia Rd and Waterloo Rd in Greenacre.

The vicious attack was captured on CCTV from the corner of the busy intersection.

Video shows the two men walking around the corner from Waterloo Rd together side-by-side, chatting as they walk.

But just moments after rounding the corner they come to a stop, as their discussion evidently turns serious.
