The scuffle was reported to have occurred on Monday around 16:45.
The pair – boys believed to be aged between 16 and 17 years old – were only said to have stopped fighting after a member of the public intervened. They then left the area.
Police described one of the teenagers as “mixed race and wearing shorts.” No information was provided about the other.
They now wish to speak with anyone with information or the boys themselves, and urge them to contact them on 612612.
