The 13-year-old, who cannot be named, was arrested on suspicion of causing actual bodily harm on the little boy, aged just three in Catford, south east London.

Mum Jade Scott had taken her two children Lilly Romain, seven, and three-year-old Ralph Cavalli to the chicken restaurant for a treat.

She said after Lilly took her little brother to the toilet, she heard a row erupting from the toilet and went to investigate. Jade claims that the older girl, who they did not know, had punched Ralph and then drop-kicked him in the face.
