Jane Fonda has been arrested for the fourth time in as many weeks protesting climate change in Washington D.C. with her actress friends Rosanna Arquette and Catherine Keener.

Arquette and Keener, both 60, were also arrested by Capitol Police.

Fonda has vowed to protest every Friday in a bid to have politicians address climate change, in an initiative that has become known as Fire Drill Fridays.

A spokesman for the group said that after her arrest, Fonda 'is spending the night in jail', Deadline reported.

Fonda had told reporters before her arrest: 'I probably will go to jail tonight. It will not be the first time. And I am prepared to do that.'
