9 year old boy slaps the heck out of his mum after finding her high on heroine on the street

A 9 year boy who found his mum high on heroine on the street, slapped the shit out her in a shocking video that was posted on instagram. The distraught little boy can be heard screaming "mummy, wake up. Can you talk to me? Wake up" while the woman stares blankly at him, making him slap her again and again. Feel so sad for the child. With a mum like this, he's probably raising himself. He shouldn't have hit her like that but I can understand his frustration. See the very sad video after the cut.
