A 12-year-old boy was assaulted by an over-protective dad in a case of mistaken identity.
The victim was in the skate park at South Park in Macclesfield when a friend he was with had words with younger boy who was pestering them.
A short time later, the little boy's dad appeared and grabbed the victim.
He demanded to know what had been said to his son and threatened to assault him.
The victim, who was sitting on a scooter, received injuries to his side.
The assault took place on Sunday, September 29, at 3pm.
PC Stephen Davenport said: "This incident appears to have arisen because of an issue which he had no part in as this was a case of mistaken identity. This was clearly distressing for the boy and we are keen to identify this man."
The man was white, 35-years-old, 5ft 6ins tall and slim. He wore an old style blue Adidas top with black stripes on the sleeves and brown chino trousers. He spoke with a local accent.
