Moment 'pyscho' pulls in front of a truck before attacking driver

A mid-traffic meltdown has been caught on camera, with dashcam footage showing a man stopping his car in the middle of a busy Sydney highway to get out and yell at the truck behind him.
Footage from the truck sent to 2GB shows a white sedan pull out from the shoulder of Henry Lawson Drive near Milperra early on Monday morning before almost immediately slamming on his breaks.
A middle-aged man gets out of the car and starts to point and yell at the driver, saying 'get the f*** out of the truck'.
The man can be heard banging on the drivers side door to the truck as the driver sits inside, presumably with the doors locked.
When his attempts to convince the truck driver to exit the vehicle fail, the sedan driver tries to face the object of his anger by climbing up the truck.
He stays there for about 15 seconds before getting down and heading back to his own car to pull over.
During this time, the truck driver calls 000 for assistance.
The matter was never resolved, with police attending the scene after both men had disappeared.
A spokeswoman for NSW Police told Daily Mail Australia officers had spoken with the truck driver and investigations were continuing.
Police encourage anyone with information or who may have seen the incident to contact Bankstown Local Police Station or CrimeStoppers.
