Indonesian officials have banned the playing of "Pokemon Go" from the presidential palace.

Hastily printed warnings that say "Playing or hunting Pokemon prohibited in the palace area" were put up around the palace complex in Jakarta on Wednesday.

Chief of the palace's press bureau, Bey Machmuddin, said, "This is the office of the president, not a playground."

Last week, Cabinet Secretary Pramono Agung said he had captured a number of Pokemon at the palace. But some officials have voiced worries that the game could be a security risk.

"Pokemon Go," which uses Google Maps and a smartphone to overlay reality with Pokemon creatures, has not been officially released in Indonesia but is already popular there.
