I guess I was right because there are now reports (ie. Sky Sports: http://www.skysports.com/story/0,19528,11095_41...) saying DIG are rejecting any media reports linking them to a bid to by Newcastle United.
The details of this story don't sound very credible, I don't think someone as desperate as Mike Ashely would laugh at a solid offer like that unless he was completely mad. This sounds like a news agency looking for the sensational headline.
