The row reportedly erupted after the driver of a blue Citroën skipped the line at a Shell garage in Welling, south-east London.
Video footage from the incident shows a man shouting out of the driver’s side window while clutching what appears to be a blade in his right hand and a plastic bag in the other.
As the confrontation escalates, the alleged knife is seen latching onto the front of the car as it wobbles forward, throwing it over the hood.
He is then filmed kicking the driver’s door and appearing to damage the exterior mirror as the car attempts to reverse.
The Metropolitan Police confirmed that they had been called to the scene Monday afternoon and that investigations were underway.

“The officers attended and found no trace of either vehicle. No injuries were reported and no suspects were identified.
“We are aware of footage online that appears to show the incident and we will be looking into this as part of our ongoing investigations,” they added.
