Pokemon Go may have played an incidental role in a series of armed robberies in Missouri.

A release on the O'Fallen, MO police department Facebook page (via ABC7 in Chicago) gives word that four suspects have been arrested on counts of multiple armed robberies in St. Louis and St. Charles counties. The police say it suspects they targeted victims through the game, and urges readers to "please use caution when alerting strangers of your future location."

In an update, the police clarified that the robbers had apparently added a beacon at a Pokestop to lure in more players, then used the app to locate people "standing around in the middle of a parking lot."

This comes just after we heard of another tangential crime connection with Pokemon Go, after a teen looking to catch a pokemon found a body floating in a river. Some edge cases are bound to happen, though, since the popularity has exploded so much that it's forced Nintendo to put the global launch on hold, and had a notable impact on the company stock. People are still looking for the creatures in all sorts of bizarre locations, but if you feel compelled to visit an empty parking lot, maybe bring a real-life Poke-buddy with you.
