Derbyshire Police warn Pokemon Go gamers of train danger

Police have also warned parents the location tracking used in the app could be used by criminals to target children

Police have issued a warning to children after some were seen playing the Pokemon Go smartphone game on a railway line.

The children in Swarkestone, Derbyshire were "risking death by a 120mph train", officers said.

The app encourages gamers to catch Pokemon characters by using their phones in "real world" settings.

A Derbyshire Police spokesman said they had spoken to the children about the dangers.

A tweet from Melbourne Safer Neighbourhood Team said: "Do not trespass on the railway to play #PokemonGO as you risk arrest but more importantly you risk death by a 120mph train."
