Just based on the logic of institutions, I'd expect all the parties involved here to start covering up before they even know themselves what the truth is.
Unfortunately online search has gone useless and it's not possible to find out if anyone ever confirmed anything about that report. Just gazillion of other newslets repeating the original claim.
