Two Canadian children illegally crossed the U.S. border while playing the augmented reality game Pokemon Go.
On July 21, border patrol agents encountered the children walking southbound from Canada into the U.S. while playing the game on their cellphones, according to a U.S. Customs and Border Protection news release.
The agents determined the children were unaware of their surroundings and did not know they had illegally crossed the border.
“Both juveniles were so captivated by their Pokemon Go games that they lost track of where they were,” public affairs officer Michael Rappold said in the release. "They crossed the international border inadvertently, but agents were able to reunite them with their mother."
The children were detained near Sweetgrass, Montana, which borders Canada’s Alberta province, until their mother arrived to take them home.
In its first week of release, Pokemon Go was downloaded more than any other app in the history of the Apple store, including Google Maps, according to GameSpot.
At its peak, Pokemon Go had an estimated 25 million users a day in the U.S., according to research conducted by SurveyMonkey. That number is now at just more than 20 million.
