Caught in the act.
A smart lady has caught a man trying not too discreetly to snap a shot of her panties while sitting opposite her on the train.
She then put it on Twitter for the world to see.
If her tweets are to be believed, she would appear to be a high school student.
This kind of thing happens every day in Japan. There are lots of perverts on the trains, including so-called respected professionals.
It reminds us of this other incompetent snapper on a train, himself photographed being none too subtle about his under-the-skirt photography.
