A nine-year old boy was punched in the face by an older man in broad daylight on Sunday.
The boy was having a row with another youngster in Manor Road Park at around 3.30pm when the man intervened and hit the victim.
As a result the boy suffered a nose bleed.
PC Andy Nicholson, of Scarborough Police, said: “Thankfully the boy’s injuries were not severe. However, the incident did leave the child upset and shaken.
“If you were in the Manor Road Park at the time, I ask you to come forward and contact the police so that I can establish the circumstances surrounding this assault.”
Anyone who can help with the inquiry is being urged to contact Scarborough police on 101, select option 2 and ask for Andy Nicholson.
