'Don't Pokémon and drive' warning from Thames Valley Police

It's the mobile app that is taking the world by storm — but Pokémon Go users have been urged to use some obvious common sense when playing the game.

Millions have signed up to play since Pokémon Go, an augmented reality game where users hunt pocket monsters with names like Pikachu and Charmander using the GPS on their phone, officially launched in the UK on Thursday.

But the app has caused safety concerns about users not paying attention to their surroundings, particularly when crossing roads or walking in congested areas.

There have even been reports of people playing the game while driving, prompting Thames Valley Police Maidenhead to issue a warning.

Earlier today, it tweeted: "Don't let us catch a peek-of-you catching a Pikachu whilst driving."
