The authorities at the US Holocaust Memorial Museum in Washington has urged visitors to not chase Pokemons on the premises as it is “extremely inappropriate”, BBC reported. The spokesperson for the museum, built in memory of those killed by Nazis during World War II, made the announcement on Tuesday, after Nintendo’s augmented reality game gained a crazed fan-following around the world.

Pokemon Go requires players to walk around specific locations in various cities till Pokemon creatures suddenly pop up on their smartphones. The aim is to collect them as you go along. Both the museum and cemetery were listed as locations where players could find Pokemons and other virtual items. Officials at both places are now trying to get themselves removed from the game’s list.

Within days of its release, the Pokemon Go app has become the top-selling app on the iPhone as well as on Android, beating old favourites such as Tinder.
