The video shows the Sikh boy in a black top knot and grey sweatshirt over his school uniform arguing with a white teenage boy as a few other schoolmates look on.
When the white boy gets physical, the infuriated Sikh boy is seen thrashing him multiple times.
However, there are no visible signs of injury on either of the boys.
The exact time and location of the video remains unknown.
Under UK reporting norms, teenagers are often not named for legal reasons of protecting their identity.
