STOCKHOLM (AP) — Swedish prosecutors have offered to question WikiLeaks founder Julian Assange in London, potentially unlocking a stalemate in an almost five-year-old investigation into alleged sex crimes.

Prosecutors had previously refused to travel to London, where Assange has taken refuge at the Ecuadorian embassy. Lead prosecutor Marianne Ny explained the change in position Friday by saying some of the crimes Assange is accused of will reach their statute of limitations in August.
