A woman driver was punched in the head by a man during a road rage incident.
The victim was assaulted in Main Road, Wilby early last Thursday morning (28 November).
At some time between 8.35am and 9am, the woman was driving her car along Main Road, Wilby.
The car was waiting in traffic and the woman allowed a few motorists, looking to join the road at a junction, to join the queue in front of her.
At this point, the driver of a black flatbed-style truck behind her sounded his horn a number of times.
The woman looked in her rear view mirror and saw the man driving the truck pointing at his watch.
Traffic then moved very slowly towards Wellingborough – the man in the truck pulled out into oncoming traffic and began to overtake the woman.
Continuing to sound the horn, the truck driver finally stopped in front of the woman, got out of the truck and walked towards her car.
He opened the car door and shouted something in an east European language, possibly Polish.
The man then punched her to the head and slammed the car door, which also struck the woman on the head, before driving off at speed.
The man is described as white, 5ft 10ins of medium build with broad shoulders and very short blond hair.
He is aged 30-40 and was wearing a light grey speckled zipped-collar jumper with a white tee-shirt underneath, blue jeans and white trainers.
He was driving a Transit-style black flatbed truck with British number plates, registration unknown.
