it now has been changed to incident http://i26.tinypic.com/2n08qav.jpg
Looks like some kind of automatic standard text that might be put on all articles in a certain category.
If you think about it, the BBC aren`t going to aren`t going to ask their audience if they were affected by the accident or incident. Or if they are, it`s a standard thing.
It may be a person chose accident instead of incident, in the message. I doubt it though.
But this doesn`t prove much
Good luck getting your anti virus running!
