WATCH: Cyclist Films Romford Road Rage
A passenger chased and threatened a cyclist in a road rage incident - unaware he was being recorded by the cyclist's helmet.
The video above shows the cyclist riding going over a roundabout on Waterloo Road in Romford, when someone in a Ford Fiesta drives shouts abuse at him.
As they stop at traffic lights ahead, the passenger gets out of the car and strides towards the cyclist, before grabbing and threatening to punch him.
The cyclist said: "I have reported this to the police and provided a copy of the video. It is a shame that a few other road users think it's okay to have a pop at cyclists. I hope this man is found soon."
