The article said nothing about that.
You (and many others) are making assumptions on few actual facts.
I'm making an assumption that as the women followed the cyclist to take a photo, it's possible that she's the one being confrontational and made potentially false statements to the police about what happened. The cyclist might well be 85 for all I know and cant climb a hill for crap, which is why a 65 year old women was maybe able to walk him down ?. Maybe the cyclist reached out to block his photo being taken and the women slipped while thinking she was about to be struck. Oh My God, another assumption.
I actually have no clue as to what happened and the article tells us very little so I'll stop making assumptions.
