Swedish authorities have turned down a request from Julian Assange to leave the Ecuadorean embassy in London without being detained to attend a funeral.
The Prosecution Authority said in a statement that nothing in Swedish legislation permits exceptions.
It is not clear which funeral the WikiLeaks founder wanted to attend.
The 45-year-old Australian computer hacker is wanted for questioning over a rape allegation stemming from a 2010 visit to Sweden.
He denies the accusation, and fears being extradited to the US to face espionage charges if he leaves the embassy, where he has been holed up for four years, to return to Sweden.
