"I don't know if you guys just heard me, but I was walking back to my RV, which is right there so that we can go back to camp peacefully and they grabbed me by my jacket and said that I was not allowed to continue," she says.
"So everybody knows... we were going to our vehicle which they had all surrounded and waiting for me with giant guns and a giant truck behind them just so they could arrest me," she continued, suggesting she was only taken in to custody due to her fame.
The star had been filming the entire experience for a Facebook Live, so she managed to capture the arrest (skip to 1 hour 55 minutes for the arrest).
The star had support from fellow actor Mark Ruffalo, and author John Green, who tweeted out their support for her protest and arrest.
