The boy reported that he was followed by three other teenagers who confronted him on Station Road, between the station and the junction with Spenser Road.
The victim was then grabbed and assaulted by the three boys and later required hospital treatment for his injuries.
An investigation is ongoing and a 14-year-old boy has since been arrested on suspicion of assault. He was later released pending further enquiries.
