Police are appealing for witnesses following an alleged assault in Swadlincote.
At around 8.40am on Saturday, August 2 a man was walking his three dogs in a field off Swadlincote Lane in Castle Gresley.
He sees another man with a chocolate Labrador walking in the same area and waits at the end of the field for them to pass. The dog however runs away from its owner towards the victim and his three dogs.
The owner of the chocolate Labrador also runs towards them and a disagreement takes place over the control of his dog. He immediately becomes aggressive and confrontational and pushes the victim, head butting and punching him.
The suspect is described as white, aged between 40 and 45 years old, of stocky build and approximately 6ft tall.
He has short, dark hair, stubble and was wearing a light blue waterproof coat and fawn coloured shorts.
The victim received injuries which are believed to be non-life-threatening.
Officers are keen to speak to anyone who may have witnessed the incident or may know who this man is.
Witnesses or anyone with information is asked to contact Derby South officers on 101 or Crimestoppers anonymously on 0800 555 111 quoting crime reference 32098/14.
