Singaporean photographer Leslie Kee and two others have been arrested on suspicion of selling photo collections containing images of male genitalia in Tokyo, an act police say constitutes illegal distribution of obscene documents.

Kee, 41, a Japan-based photographer known for his published works featuring celebrities such as Lady Gaga, and two Japanese organizers of a photo exhibition allegedly sold photo books containing the images, police said, adding that most of the pictures in the 50-page book showed male genitalia.

The two Japanese are 45-year-old Hiromi Yoshii, an executive of a company operating a gallery, and 27-year-old Yuko Kanda, an employee of the firm.
