The rare Pokémon Lapras caused a frenzy among hundreds of Pokémon GO players when it appeared off the coast of Tokyo on Sunday afternoon.
Local police were dispatched to Odaiba, a man-made island located to the south of Tokyo, after receiving multiple complaints of people — Trainers — acting bizarrely, NHK News reports. Stopping traffic, running left, running right — multiple crowds of people moved in unison, many times aimlessly, like large schools of fish strategically targeting their prey.
Due to the safety concerns, authorities have contacted Niantic Labs in hopes of making Odaiba Island a safer place for locals.
“People have driven Lapras almost to the point of extinction,” according to the dual Water/Ice-type Pokémon’s description in Pokémon Omega Ruby & Alpha Sapphire on Nintendo 3DS. “In the evenings, this Pokémon is said to sing plaintively as it seeks what few others of its kind still remain.”
No injuries were reported during the turmoil. Meanwhile, however, one Pokémon GO player in New York City was recently mugged while live-streaming on Twitch.
Pokémon GO launched on Android and iOS mobile devices in several countries, including Japan, in July. Since its release, the free virtual Pokémon-catching game has amassed more than 500 million worldwide downloads.
