40 year old Tetsuya Fukuda has been caught and arrested. It is guessed that he may have cut holes in his jacket so he was able to masturbate without people knowing about it.
He was finally caught when a DNA test showed inconclusively that he had ejaculated on a school girls skirt.
When arrested he was quoted as saying:
” I get excited when in close contact with a woman on a crowded train.”
After his arrest another of his surprised victims came forward saying:
“It happened to me as well but I didn’t know who had done it. It is just disgusting, he needs help.”
