Niantic, the developers of the game, have issued a statement saying they take player safety seriously.
It reads: “We encourage all people to be aware of their surroundings and to play alongside friends or family, especially when you’re exploring unfamiliar places,” he added.
“Please remember to be safe and alert at all times, don’t drive and play, abide by local laws and respect the locations you visit.”
A spokesperson for Lancashire Police said: “People should avoid potentially dangerous locations that could make you vulnerable to injury or become a victim of crime.
“Never enter any body of water. Pokemon do not appear beyond the safety of the shoreline. And don’t enter derelict structures, unlit footpaths or alleyways.”
