BBC not aware of 'deeply disturbing' specifics, says Davie
The police told the BBC in November that its chief presenter Huw Edwards had been arrested, but asked the BBC to keep that information secret, Tim Davie says.
The BBC director general told correspondent David Sillito he thought it was right not to have sacked Edwards after his arrest in November.
Edwards kept his job despite the BBC knowing he had been arrested over the most serious category of indecent images of children.
