A 15-year-old boy known to police for flying drones in crowded places was arrested Thursday on suspicion of planning to fly one of the devices at a Tokyo festival.

The boy, who lives in Yokohama, is suspected of posting a video message online last week in which he implied he might fly a drone at the Sanja Matsuri festival at Asakusa Shrine, according to police.

"Tomorrow it seems there is a festival in Asakusa. I will go. No signs they're banning movie shooting," the police quoted the boy as saying in the video. The festival will be held on Friday and Saturday.
