Beds Police are appealing for witnesses after a 62-year-old driver was assaulted in the car park of the Co-operative store in Barton Le Clay.
The incident happened on Saturday, August 2 between 4pm and 5pm as the victim was parking in the Bedford Road car park.
A very tall, stocky white man got out of a white van and approached the victim shouting abuse.
He then hit the victim several times before getting back in to the van and driving off.
The victim was left with bruising to his arm and face and a twisted knee joint.
PC Barry Smith, investigating, is keen to trace other motorists and shoppers in the area at the time of the incident.
PC Smith said: “This incident happened during daylight hours in a busy car park.
“There was a lot of shouting prior to the assault which would have drawn the attention of people in the area and I would urge these people to come forward and tell officers what they heard and saw.”
Anyone with information relating to the incident can contact PC Smith, in confidence, at Luton Police Station, on 01582 394217, or Bedfordshire Police on 101.
