Drunk' Japanese businessman walks the wrong way down Tube escalator.
The man - wearing a suit and carrying a briefcase - appears unsteady on his feet as he tries to make his way down the escalator at Tottenham Court Road tube station.
Bemused commuters try to help him off, but he ignores them and continues to try and walk the wrong way.
After struggling for two minutes as people push past, he is guided away by a helpful commuter who pushes the emergency stop button and points him in the right direction.
