A lorry driver had to intervene when a driver got out of his car and assaulted another motorist after grabbing his face.
The victim was driving behind a brown hatchback car, which had a registration starting B06 and kept braking heavily, in Northfield Avenue, Kettering, between 1.45pm and 2.20pm on Monday (January 25).
At some point the driver of the hatchback stopped his vehicle and confronted the victim, who also got out of his car.
The offender grabbed at the victim’s face, causing cuts to the cheek and nose.
The suspect is described as about 70, 5ft 5in with a Scottish accent, a stocky build and short grey hair and a grey beard.
A police spokesman said: “A man, believed to be a lorry driver, intervened and separated the victim and offender.
“We are appealing for this man to get in touch.”
