How the Coronavirus cluster in Aberdeen started

I have no proof or evidence of the following but received this information from a trustworthy source:

"Apparently a French oil and gas worker heading offshore got to the helipad at Aberdeen Airport but was refused entry to the helicopter because he tested positive for coronavirus.

He was told to isolate but instead went to the Spider's Web pub at Dyce, and then onto a pub crawl round Aberdeen over the next few days. This all started 26 July. Hence the various pub venues affected by this incident."

Is it true?

Sorry, that's all I know. But I did not make this up.

Aberdeen - all that's left to do is walk the streets
