Police had to be summoned to deal with a massive crowd of Pokémon GO players following a Lapras sighting in Tokyo's Odaiba district.

Reports of the monster's existence caused hordes of players to descend on the location, with many spilling onto the road and causing a safety hazard. Some have even gone as far as to name the event "Lapras Panic" on social media channels.

According to NHK, the police have contacted The Pokémon Company and developer Niantic to ensure that Lapras doesn't spawn in the same location again, and instead appears somewhere a little safer.
