Police said they arrested 34-year-old Hironori Saeki late Thursday on suspicion he took video footage of the underwear of a 16-year-old high school girl in Yokohama, the summit host city southwest of Tokyo.
Saeki reportedly used a digital camera hidden in a bag placed under the victim's skirt as she stood on a train station escalator.
Saeki was among police reinforcements dispatched from northern Miyagi prefecture as part of Japan's security plan for an Asia Pacific Economic Cooperation summit next month.
"It's very regrettable as it was an act by a police officer, which must not be tolerated," said Miyagi prefecture police senior officer Kunimitsu Yoshida in a statement.
