Lucia C. was found “injured and disorientated” and was taken to hospital, Vaud police said in a statement on Tuesday.
Investigations are underway to determine what happened to her. No other information will be given at this stage, added police.
The 23-year-old Spaniard was last seen by friends on Friday night but then vanished.
On Saturday morning the car she was using – a grey Audi A3 – was found damaged at Monts-de-Corsier above Vevey, not far from the family home where Lucia was working as an au pair.
