The source further noted that Quito already has an agreement with the UK for the arrest, according to a Thursday tweet by WikiLeaks.
The founder of the document leaking and publishing website has dismissed the allegations as "completely bogus."
The Ecuadorian Foreign Ministry said it did not comment on claims about the possible expulsion of WikiLeaks founder Julian Assange from the Ecuadorian embassy in London, calling these claims "rumours."
"Ecuador does not respond to rumours, speculations and assumptions which are not supported by any documents," the ministry said, as quoted by the Comercio news outlet.
