Julian Assange will face questions in London next week over the 2010 allegations of sexual assault that led to his confinement in the Ecuadorean Embassy, Swedish prosecutors said Monday.

“Ecuador has granted the Swedish request for legal assistance in criminal matters and the hearing will be conducted by an Ecuadorian prosecutor,” the prosecutor’s office said in a statement. The statement added a DNA sample will be taken, “provided that Julian Assange agrees to it.”
