Guardian columnist Stuart Heritage wrote a column last month on reasons to love winter. You can read it here.
Earlier this morning it was brought to his attention that his column may have been plagiarised by columnist Carly Fallon from The Press And Journal, a local newspaper for Aberdeen.
He then tweeted her article for others to compare to his own.
Here's what I have worked out.
Update - Lucy Mangan, another Guardian columnist, has accused Carly Fallon of plagiarising one of her articles for the same column. This is an article she wrote in 2009.
Rhiannon Lucy Cosslett has also accused Carly of doing the same. Here is a piece she wrote on Tuesday.
Twitter users even mentioned that a recent Jan Moir column from the Daily Mail has strikingly similar words to her column.
There are also similarities with a Toby Young column from "The Spectator" written in 2011.
Update (5:02pm GMT) - Damian Bates, Editor of The Press And Journal has issued this statement:
"Obviously plagiarism – in any form – is totally unacceptable.
"I take this matter very seriously indeed and have decided that we will no longer be accepting columns from freelance writer Carly Fallon.
"I'm deeply disappointed this situation has arisen and apologise for any upset this has caused anyone."
