Basically in 2017 a confidential source CS told the editor for Fast Company FC that some random investor Shervin Pishevar VC was arrested by London police in May 2017 for suspicion of sexual assault. VC then confirmed the arrest to FC.
FC published an article on this in late 2017 using a police report provided by CS. However the report turned out to be fabricated, and I guess London police dragged their feet on authenticating it before the FC article was published.
VC in 2019 subpoenas FC for docs related and to try to get the name of CS. FC complies mostly but doesn't give up the name of CS on principle.
Basically, VC admitted to being arrested for something, but FC received a fabricated report from CS, not the real one? Wild.
It's hard to know who is really in the right. At first glance this is VC trying to suppress press freedom, but if the report was fabricated, maybe VC is morally unblameworthy in seeking the report via the threat of legal action. Perhaps it depends on the delta between what really happened/was published/the real police report and the fabricated report.
