A simple tale of a Cardiff mum's anger at yobs on a train took a dark twist when the Press Association sent out an illustration with the news story - a picture of the Auschwitz rail tracks.

Blamed on "human error", the picture appeared alongside the story on local newspaper websites including the Cambridge News. PA apologised and removed the picture, saying in a statement: "We apologise for any offence caused by this unfortunate human error.

"The photograph was removed from the story as soon as we realised the mistake and we have taken steps to ensure this does not happen again in the future."

It's only an assumption, but...perhaps this is what happens when a picture researcher types "railway" into the search and doesn't think to look at the building at the end of the line.
