Heroic commuter stands up to 'racist' who was 'picking on young boy'.A brave passenger confronted a drunken man who was allegedly racially abusing a boy on a busy overground Tube.

Boozed up and swaying, the man was filmed slurring abuse at a younger commuter - who was out of shot.

The heroic bystander can be heard saying: "What's the point in being racist? What do you want?

Unbelievably he sarcastically knocks against the train cabin wall and replies: "I'm racist because you're stupid."

The man then replies: "For what? For sitting here and doing nothing? I'm stupid?"

The older man, presumably in his 50s, was dressed in a white t shirt, shorts appears to say: "You're doing something. You're a citizen here for some reason."A brave passenger confronted a drunken man who was allegedly racially abusing a boy on a busy overground Tube.

"I wish I could have done exactly that but I don't quite have the shoulders for it."
