LONDON — Julian Assange, founder of WikiLeaks, has won his battle against extradition to Sweden, which wanted to question him about a rape allegation. He has spent nearly five years inside the Embassy of Ecuador in London to avoid being sent to Sweden, which announced Friday that the investigation has been discontinued.

Here are key events in the Assange saga:

2010

Aug. 31: Swedish police question Assange, who denies the allegations.

Sept. 1: Sweden's director of prosecutions, Marianne Ny, reopens rape investigation.

Sept. 27: Assange leaves Sweden for Britain.

Nov. 18: Stockholm court approves request to detain Assange for questioning.

Nov. 20: Swedish police issue international arrest warrant for Assange.

Dec. 8: Assange surrenders to police in London and is detained pending extradition hearing.

Dec. 14: Assange is granted bail but prosecutors appeal.

Dec. 16: High Court grants bail. Assange is released after supporters pledge 240,000 pounds ($375,000) in cash and sureties.

June 12: Assange asks Supreme Court to reopen case.

June 14: Supreme Court refuses to reopen case.

June 19: Assange enters Ecuadorean embassy in central London, seeking asylum. Police set up round-the-clock guard to arrest him if he steps outside.

Aug. 16: Assange is granted political asylum by Ecuador.

2013

June: Assange tells journalists he will not leave the embassy even if sex allegations against him are dropped because he fears he will be extradited to the United States.

2014

July: Assange loses bid to have an arrest warrant issued in Sweden against him canceled. A judge in Stockholm upholds the warrant alleging sexual offences against two women.

September: Assange's lawyers submit a complaint against Sweden and Britain to the U.N. Working Group on Arbitrary Detention claiming his situation in the embassy amounts to illegal detention.

November: Assange loses a legal move in a Swedish appeal court aimed at revoking his arrest warrant.

Aug. 16: British Foreign Office Minister Hugo Swire says Ecuador's decision to harbor Assange had prevented the proper course of justice.

Oct. 12: Metropolitan Police end their 24-hour guard outside the Ecuadorean embassy but say they will use overt and covert means to track and arrest Assange if he leaves. It ends a three-year police operation which is estimated to have cost more than 12 million pounds ($17 million).

2016

Feb. 5: Assange claims "total vindication" as the U.N. Working Group on Arbitrary Detention finds that he has been unlawfully detained and recommends he be immediately freed and given compensation. Britain and Sweden say the finding will have no impact on their policy. British Foreign Secretary Philip Hammond calls the finding "frankly ridiculous."

2017

Jan. 19: Assange retreats from offer to accept extradition to the U.S. if Chelsea Manning was granted clemency. His lawyers say Assange was really asking for a pardon for Manning.

April 6: Ecuador's president-elect, Lenin Moreno, warns Assange that as a condition of asylum granted in 2012, he is not allowed to meddle in politics. The rebuke followed Assange's Twitter blast at the losing candidate.

May 19: Prosecutor Marianne Ny announces that investigation has been suspended and the European arrest warrant has been withdrawn because she sees no realistic possibility of bringing Assange to Sweden. British police say he is still wanted for jumping bail in 2012.
