A man was assaulted with a cricket bat after a road rage incident on the A14 between Kettering and Rothwell.
The victim, who was in a white Mercedes ML, was driving eastbound shortly after 1pm on Friday (April 1) when the driver of a grey BMW 320D - who was allegedly driving very close behind the Mercedes - gestured to the driver to pull over.
The Mercedes driver continued along the A14 and, just before the Rothwell Lodge cottages, the BMW pulled in front of the Mercedes driver, causing him to swerve on to the grass verge.
Both men got out of their cars and the driver of the BMW shouted at the victim before getting a cricket bat out of his boot.
The Mercedes driver started to walk away when he was hit on the back of his legs with the bat, causing him to fall to the ground.
The offender is described as white, about 30 years old, 6ft 5in and stocky with an athletic build.
He had short, dark brown hair and a beard, and was wearing a T-shirt and jeans. The BMW had a 2015 plate.
Witnesses, or anyone with information, are asked to contact police on 101 or Crimestoppers anonymously on 0800 555111.
