"This morning at approximately 2 am we responded to the report of an Armed Robbery near the intersection of Highway K and Feise Road", the O'Fallon Missouri Police Department said in a statement.
Missouri police are investigating a series of armed robberies involving the new smartphone app Pokemon GO.
About eight or nine people have been robbed by four men over the past couple of days, a spokesperson from the O'Fallon Police Department told Gizmodo over the phone.
"Nobody was hurt, and no shots were fired in ours", he said, referring to the robbery that took place in his jurisdiction.
Police say that the suspects set up a beacon to a Pokestop -virtual sites in the app that can be designated at any real word location- to lure players.
According to police, the four used the app's Global Positioning System feature to find players who had gathered in parking lots and other open spaces.
Many of you have heard of Pokemon Go, but for those that have not, it is a type of Geo Caching game where you find and capture Pokemon characters at various locations.
