The parents of a Swedish programmer suspected of plotting to blackmail Ecuadorian President Lenín Moreno over his abandonment of WikiLeaks founder Julian Assange say their son is innocent and that his rights have been violated.

At a press conference Tuesday in Ecuador's capital, Dag Gustafsson and Gorel Bini said they will remain in Ecuador until their son is released.

Authorities arrested 36-year-old Ola Bini hours after Moreno chose to end Assange's asylum in the nation's London embassy last Thursday.

Prosecutors have said they intend to charge Ola Bini with hacking-related crimes and have ordered him detained for up to 90 days while they compile evidence.

The man's parents acknowledged that their son had a relationship with Assange but denied that he had any involvement with WikiLeaks.
