An elderly man was left bloodied and bruised in a “vicious” attack in Thornton.
Police are appealing for help to identify a couple they believe assaulted the man as he walked his dogs on the playing fields behind Marsh Mill.
The victim was treated in hospital for his injuries, which included a bloody nose, a cut arm and a suspected broken tooth, following the attack at around 4.30pm on March 4.
PC Maura Bunn, of Fleetwood Police, said: “This was an unprovoked vicious attack on an elderly man where they have just left him without checking he is OK.”
It is thought a dispute may have begun following complaints over the behaviour of the couple’s dog.
PC Bunn said the dog behaved threateningly but had no physical contact with the victim. No dogs were attacked.
The man is described as medium height, slim and with short hair and stubble.
Police said the woman is of a similar height, a larger build and has long curly auburn hair.
Both are thought to be in either their 20s or 30s.
Officers believe they regularly walk the tan, brown or black coloured Alsatian and German shepherd cross-breed dog on the fields.
PC Bunn said she hoped residents in the area would be able to help them identify the couple.
She added: “We are appealing to anyone who saw this incident or anyone who has had dealing with these two and who have any idea who they are.”
Anyone with information is asked to call PC Maura Bunn at Fleetwood Police on 101.
