Developer Niantic Labs has confirmed it has removed the legendary Pokémon Articuno from players' accounts in its hit augmented reality game Pokémon Go.

Articuno is the first legendary Pokémon creature to be spotted in the game. IGN reports that one player in Ohio claimed Niantic added Articuno to his Pokémon Go account as an apology for an issue he reported in the game.

However, it looks like Articuno was released too early, according to an official statement from Niantic:

"We recently noticed that a few Legendary Pokemon got into a few accounts when they shouldn't have, To preserve the game's integrity and as a measure of fairness, we have rectified the situation and revoked the legendary Pokemon from the Trainers' accounts."

There's no word on when these legendary Pokémon will officially be made available to Pokémon Go players.
