Pokemon GO players got something they weren’t looking for when they were playing with the app at Harbour Square Park in Toronto, Canada — being shot at. According to the Toronto Star, a group of Pokemon GO players was shot at by a 29-year-old woman on Saturday night. Police were called to the Newmarket area at around 10:30 p.m. Saturday, according to the police statement on Monday. Instead of preventing players from going to the area to play Pokemon GO, players were out in force in the Newmarket area after the statement was released.

A Canadian woman has been charged after she allegedly fired a pellet gun at Pokémon Go players from the rooftop of a Toronto-area home, local police said on Monday.

Witnesses saw the 29-year-old woman fire at least four shots on Saturday night from the roof of a two-story building, police said in a statement, adding that no players were injured.

A police spokesman said part of the street in the town of Newmarket, north of Toronto, had possibly been marked in the augmented reality game as a “gym”, where players gather to challenge each other.

It is not immediately clear how many Pokémon Go players were on the street that night, though the police spokesman said the area has attracted them by the dozens.

“There’s nothing to suggest mental health issues,” he said.

Police said the woman was arrested without incident and charged with assault with a weapon and possession of a weapon for a dangerous purpose. Each of the charges carries a maximum penalty of 10 years in prison.

Nintendo shares plummet after it points out it doesn’t make Pokémon Go

Pokémon Go has been an unexpected success from Spain to Australia, doubling the value of Nintendo Co Ltd since the game’s launch in the United States earlier this month.

Using mobile devices, players search for virtual Pokémon characters that appear to pop up at office spaces, restaurants, museums and other places. Players score points in various ways, including capturing the Pokémon characters with a flick of a finger on their phone screen.

The game was also to blame for a rash of car accidents and a slew of mishaps stemming from distracted players.

York regional police, which oversees Newmarket, said officers have received “a number of” calls from concerned citizens about people playing Pokémon Go, and while there’s nothing illegal about partaking in the game, players should be careful not to trespass.

Last week, two youths in Canada unaware of their surroundings when they were playing Pokémon Go made an illegal border crossing into the United States.
