Assange, 45, took refuge in the embassy in June 2012 to avoid extradition to Sweden over the rape allegation, which he denies.
Assange has been living in the Ecuadorian Embassy in London since 2012 fearing that his arrest might result in extradition to the USA, and a U.S. trial over the leaks of hundreds of thousands of classified documents of the American government.
The dropped charges follow a series of interviews by Swedish prosecutor Ingrid Isgren at the Ecuadorian embassy.
But it adds that Assange is.
Later he tweeted again: "Detained for 7 years without charge by while my children grew up and my name was slandered".
Samuelson said he did not know if Assange would leave the embassy building in London and try to go to Ecuador.
Assange told reporters Friday he would be happy to discuss his case with the U.S. Department of Justice.
Asked at a Conservative campaign event in Edinburgh if the United Kingdom would now support a request to extradite Assange to the US, Theresa May said: "We look at extradition requests on a case-by-case basis". CIA Director Mike Pompeo has branded WikiLeaks a "hostile intelligence service", and Attorney General Jeff Sessions said last month that Assange's arrest is a priority.

Attorney General Jeff Sessions has suggested that the arrest of Assange could be an American priority, saying last month the USA was "stepping up our efforts on all leaks".
British officials said they do not comment on individual extradition cases.
WikiLeaks founder Julian Assange says his legal team will contact United Kingdom officials to seek a way forward in resolving in resolving his status. However, British police say Assange still faces arrest for jumping bail if he leaves the Ecuadorean embassy in London.
The European arrest warrant was issued in 2010 after two women came forward saying they had been sexually assaulted by Assange.
Assange has said that all the sex was consensual.
"My client is shocked and no decision to [end the case] can make her change [her view] that Assange exposed her to rape", she said.
Sweden's top prosecutor says the investigation of alleged sexual offenses could reopened if Julian Assange returns to Sweden before the statute of limitations lapses in 2020.
Senator: Trump Russia investigation appears to be criminal investigation
Rosenstein announced Mueller's appointment yesterday. "I find it hard to subpoena records of somebody like Mr. She addressed reporters after a closed-door meeting where Rosenstein briefed senators.
Another lawyer, Christophe Marchand, told AFP that "We have been waiting a long time for this decision".
Samuelsson, the lawyer in Sweden, told Swedish Radio he had been in touch with Assange via text message and the Australian had written, "Serious, Oh My God".
The Metropolitan Police Service in London said after the news was announced that it remained obliged to arrest Assange should he leave the Ecuadoran embassy on a lesser charge of failing to surrender to a court, the BBC reported. British police said before the announcement that Assange is still wanted in Britain for jumping bail.
But it added that Assange is now wanted for a "much less serious offense" than the original sex crimes claims, so police "will provide a level of resourcing which is proportionate to that offense".
The Metropolitan Police stopped its round the clock presence outside the Embassy in October 2015 amid controversy over the escalating cost of the exercise - believed to be over £12 million.
It's not known if US officials are seeking Assange's arrest because of a possible sealed indictment.
During the most recent US presidential election campaign, WikiLeaks published emails from Hilary Clinton's staff and the Democratic National Committee which some believe helped to lose her the election. She was freed Wednesday, having had her sentence commuted by outgoing President Barack Obama before he left office.
