A New Hampshire day care center was removed from Pokemon GO after complaining to the game's developers about strangers lurking around the property.

Little Blessings Child Care Center director Diane Lewis sent a letter to parents and the day care's two dozen employees explaining the issue, the Portsmouth Herald reported.

Lewis claimed she'd seen random people in the day care's parking lot and walking the grounds since the game launched last month. The Portsmouth center appeared as a "gym" in the game.

The director said she got in touch with game developer Niantic Labs and had the facility removed.

She says Little Blessings' presence in the game was a safety concern and she was glad it was dropped.

"If you see anyone parked in the parking lot or walking around the property with their cellphones that you do not recognize, please make a point to ask them to leave," she added in the letter.

Pokemon GO has triggered its fair share of headaches across the country. 

The location-aware game provides virtual rewards for players who visit real sites designated as "Pokestops" in the game. Several locations, such as the Hiroshima Peace Memorial Park in Japan and the Arlington National Cemetery in Washington, D.C., have asked to be removed from Pokemon GO.

And, a man in New Jersey said he was taking the makers of the game to court. Jeffrey Marder claimed strangers began lingering outside of his home after the game was released. At least five people knocked on his door and asked to get into his backyard to catch a Pokemon placed there, according to a lawsuit filed Friday in federal court in California.
