Japanese police arrested a 27-year-old man aboard a plane Tuesday as he was being deported by Philippines immigration authorities, for allegedly operating an illegal manga-viewing website that hosted copies of popular comics such as "One Piece."

Romi Hoshino, who had been wanted over copyright infringement for running the now-closed pirate site Manga-Mura, was being sent back from the Philippines, where he was detained in July while on his way to Hong Kong, at the request of Japanese authorities.

Hoshino allegedly headed the operation of the website, which is believed to have caused damage valued at over ¥300 billion ($2.8 billion) to the manga industry by distributing unauthorized image files of popular series.
