HUDSON FALLS -- Pokemon Go is proving to be a problem for Hudson Falls Police.

A brawl that involved an estimated 30 people broke out Saturday night at Juckett Park, and police believe the participants were among groups of young people going to the park to get a "gym" as part of the online game craze Pokemon Go. A video of the fight was posted online early Sunday.

Hudson Falls Police Chief Randy Diamond said police have repeatedly had to roust visitors from the park after hours as crowds gather there to get a virtual reality "gym" that is part of the game.

The Main Street park's curfew is midnight, and police have had to ask players to move along a number of times in recent weeks, Diamond said.

One person suffered minor injuries and no arrests were made. But Diamond said police plan to review the video to see if they can identify the participants and whether any charges such as disorderly conduct are warranted.

Diamond said as many as 50 people were in the park when the fight happened before midnight. It appeared to start with two people who had prior issues with each other, and escalated to dozens of others "pushing and shoving," the chief said.
