The wife of news reader Huw Edwards has named him as the BBC presenter at the centre of the allegations.
In a statement issued on his behalf, Vicky Flind says her husband is "suffering mental health issues" and is now receiving in-patient hospital care.
Detectives from the Met Police have ended their inquiry into a BBC presenter and determined there is no evidence a criminal offence has been committed.
The BBC says it is now resuming its investigation "whilst continuing to be mindful of our duty of care to all involved”.
