Two Pokémon Go players have been mugged at gunpoint while playing the game in a New South Wales park at night.

The couple, both aged 29, drove to a skate park at Tahmoor at 7pm on Wednesday where they found their way blocked by a white ute after entering the car park.

It is alleged two men wearing balaclavas then sprang out and threatened the pair with a rifle before fleeing empty-handed.

Police say there is no suggestion the men used the game to lure people to the area.

On Thursday police expressed safety concerns about the global craze, which directs users to capture imaginary creatures superimposed onto the real world, after two 17-year-olds were caught playing Pokémon Go while driving near a busy pedestrian crossing in Cabramatta.

Earlier this week in the US, Missouri police said they believed the app’s geolocation feature had been to lure “unwitting victims” into isolated areas and rob them.
