An immigrant woman who scaled up the stone pedestal of the iconic Statue of Liberty to protest Donald Trump's controversial "zero tolerance" immigration policy has been arrested after a three hour-long standoff with the police amid US' Independence Day celebrations.

The 44-year-old woman identified as Therese Patricia Okoumou, an immigrant from Democratic Republic of the Congo staged the dramatic protest against Trump's tough immigration policy that has separated nearly 2,000 children from their parents.
