WikiLeaks founder Julian Assange will be questioned for a second day inside the Ecuadorian Embassy in London over a sex allegation.
Swedish prosecutor Ingrid Isgren and Swedish police inspector Cecilia Redell will once again interview Assange through a representative of the Ecuadorian government.
They said a DNA sample will be taken if he gives consent.
It is believed Assange was "fully cooperative" during their initial meeting on Monday.
The process could take three days, before Swedish authorities decide on their next move.
However Ms Isgren will not be giving interviews during her stay in London.
A statement said: "As the investigation is ongoing, it is subject to confidentiality.
"This confidentiality also applies according to Ecuadorian legislation for the investigative measures conducted at the embassy.
"Therefore, the prosecutors cannot provide information concerning details of the investigation after the interview."
Assange was granted political asylum by Ecuador in 2012 and has lived in their embassy ever since.
He fears that if he leaves, the UK government will extradite him to the US for questioning over the activities of Wikileaks.
Assange has always denied the allegations against him, and has offered to be interviewed at the embassy several times.
