Corner Francis street and Williamstown road. I thought some cager had broken down do I stopped and asked if he needed a hand. He had a tyre iron in his hand so I guessed it was a flat. Traffic was going ballistic behind him. He said yeah, gimme a hand - then stormed over and smacked some bloke from the van in front of him over the head with the tyre iron like he f*cken meant it. Whack! Took a bloody good chunk of skin with it. The two blokes from the van grabbed a bunch of tie-downs and started swinging them like grappling hooks trying to nail the big guy with the tyre iron. The bloke who'd been beaned had a face full of blood like something from a horror movie. They were clearly shitscared of the big bloke. He took a few more swings, screaming at the top of his voice, then stepped back a bit. I told him he should probably get in his car and piss off, and he did. I must say, a proper bit of barney that. And probably because somebody didn't indicate early enough or something.
