To some extent, internet chatter could be ignored, but now there's something in print from one of the papers.
In this day and age, I wouldn't be surprised if the papers just picked up the Internet rumors and printed them as fact without bothering with fact-checking or anything else resembling actual journalism.
I've been following these rumors, and Ethiopia has never been cited as a potential source of recoveries for the purported 90-ish. Heck, the country didn't even get the Troughton episodes. In that regard, the Sunday People report isn't accurate and is probably errant nonsense, because there wouldn't be 100-plus episodes to recover from there. (The Ark of the Covenant, on the other hand...

So, no, Ethiopia is a new angle and the Sunday People didn't simply regurgitate internet chatter to get their article of errant nonsense.
