Canada Teens Detained After Illegal Border Crossing Into US While Playing Pokemon Go

A couple of Canadian teens walked from Alberta into Montana while searching for creatures that exist only on their phones.

The Pokeball of embarrassing incidents caused by the explosively popular game Pokemon Go rolls on.

This time it was across international borders.

According to the U.S. Customs and Border Protection, two Canadian teens illegally walked across the border into the U.S. while hunting Pokemon.

Agents encountered the teens walking Alberta into Montana while playing the location-based game this week, officials said.

“Both juveniles were so captivated by their Pokemon Go games that they lost track of where they were," officer Michael Rappold with U.S. Customs said in a statement.

The agents quickly determined the teens had crossed the border near Sweet Grass, Montana on accident and were unaware they'd even done so and contacted their mother.

"They crossed the international border inadvertently, but agents were able to reunite them with their mother," the statement said.

Pokemon Go was downloaded by more people in its first week on the Apple store than any other app in history.

And with that popularity have come a barrage of odd incidents tied to players' desire to catch 'em all, like Wyoming woman discovered dead body in a river after climbing a fence while playing the game or the New Jersey woman who called 911 after finding herself stuck in a cemetery tree while playing the game.
