London Police made the announcement on Thursday night (AEST) that they had taken him into custody - but Wikileaks claimed that Ecuador had "illegally terminated" his political asylum by inviting police into the embassy to arrest him.
U.S. President Donald Trump said on Thursday he did not have an opinion about the arrest of WikiLeaks founder Julian Assange, who faces the prospect of extradition to the United States over the publishing of secret official information. He first holed up in the embassy when Sweden tried to extradite him because of sexual assault allegations, reported BBC.
Assange strongly denied the charges and Sweden has since withdrawn its arrest warrant.
Wikileaks founder Julian Assange has been arrested by London police at the Ecuadoran embassy after that country dropped his diplomatic protection. "Nearly 7 years after entering the Ecuadorean Embassy, I can confirm Julian Assange is now in police custody and rightly facing justice in the UK".
Washington has been seeking to prosecute Assange for espionage since 2010.
However, it is unclear whether that could change if USA prosecutors are able to provide assurances to Britain that Assange would not face the death penalty if he was brought to trial.
"We're not making any judgment about Julian Assange's innocence or guilt", Hunt added, "That is for the courts to decide".
"Ecuador has illegally terminated Assange political asylum in violation of worldwide law".
British Prime Minister Theresa May welcomed the news of the arrest, saying it proved "that in the United Kingdom, no one is above the law".
He claimed asylum on the grounds that he feared ultimate extradition to the U.S., where he faces a possible death sentence or torture for Wikileaks' alleged leak of American secrets.
"When I saw Julian on Friday, he clearly expected this - in fact, I think half the press crop were outside the embassy, expecting it on the weekend", said Vaughan Smith, a freelance journalist and friend of Assange.
The London Metropolitan Police's arrest comes after Ecuador revoked his asylum.
Moreno specifically cited WikiLeaks' release of a batch of Vatican documents earlier this year, before listing a number of activities at the embassy in London that he did not agree with.
