notentirelyallhere, your post is idiotic, there are a huge number of French residing in and around London, the largest gathering of that nationality outside France I believe. You seriously think this random act of aggression was triggered by hearing French spoken, amongst the multitude of other languages anyone in London will hear. We can't know what triggered such an awful happening, but I suspect mental health issues, hallucinatory drugs.
I hope the little boy makes a full physical recovery, no doubt he will be mentally scarred by what has happened to him, but our hearts go out to him and his mother.
