WikiLeaks founder Julian Assange was being questioned by prosecutors Monday at the Ecuadorean Embassy in London about possible sexual misconduct committed in Sweden six years ago.

Assange was being interviewed at the embassy where he sought refuge more than four years ago. The questioning was being led by an Ecuadorean prosecutor in the presence of Swedish prosecutor Ingrid Isgren and a Swedish police investigator.

Prosecutors planned to ask Assange to consent to providing a DNA sample.

Swedish officials are seeking information related to allegations of serious misconduct made by two Swedish women he met in 2010. Some of the alleged misconduct is no longer being investigated by police because of the statute of limitations.

He is, however, being questioned about a possible rape of one of the women who complained to authorities. He has not been indicted.
