Police are appealing for witnesses after a man delivering leaflets was bitten by a dog in Copthorne.
The 60-year-old victim was walking in Brookhill Road when he was bitten by a dog being walked by a man.
After the incident, the owner of the dog walked off with the animal towards the Prince Albert pub.
The dog was small and white with patches of brown on its head. It also had short fur and a long pointed snout.
A Sussex Police spokesman described the dog owner as white, aged about 60 and balding, with short light hair. He was wearing a grey short-sleeved top and light-coloured trousers.
PC Richard Davies said: "The owner of the dog may live very close to where the incident happened, so we are hopeful that someone will recognise the description of him or his animal.”
He said: "If you know who or where the man is, or you saw the dog bite the victim, please contact me."
Anyone with information on the incident, which happened on Monday, June 16, at about 10.30am, should call 101, quoting serial 373 of 16/6, or email: firstname.lastname@example.org Alternatively, people can call the independent charity Crimestoppers anonymously on 0800 555111.
