The 64-year-old victim, from Sandy, was punched to the ground in the Asda car park in Biggleswade on Saturday afternoon (August 3). He was taken to Addenbrookes Hospital, in Cambridge, where he died yesterday (Sunday). A 65-year-old man was arrested later that day at his home nearby in connection with the assault. He was bailed last night until August 19.Detective Chief Inspector Tim Redfearn, who is leading the investigation, said: The men were waiting in the disabled parking area at the time and got into a disagreement about parking. We know they became involved in a disagreement which resulted in one man punching the other knocking him to the ground. It would seem an argument over nothing has led to tragic and devastating consequences for both men and their families. I know the supermarket car park would have been very busy on a Saturday afternoon so if you were there at the relevant time please contact the police in confidence.INFORMATION: Anyone with information should call Bedfordshire Police on 101 or Crimestoppers, anonymously, on 0800 555 111.
