Pokéfans negotiating Oxford Rail Station have been warned to keep their wits about them while trying to catch 'em all.

Since Pokémon GO arrived in the UK last week people of all ages and walks of life have downloaded the app in their thousands.

Following concerns being raised nationally for the safety of those glued to their screens while commuting, a sign has been put up in the foyer of Oxford Rail Station by Network Rail.

It reads: "Enjoying Pokémon GO? Please consider the following.

"Remember to stop, look and listen when approaching the railway.

"Concentrate - it's easy to get distracted by your phone, music or by catching Pokémon.

"It is illegal and very dangerous to trespass on a railway - don't risk it for a game."
