Daryl Hannah - Daryl Hannah Arrested After White House Protest

The Splash star joined dozens of environmental activists outside the White House for a sit-in protest about a proposed plan to build the Keystone XL pipeline, which would stretch from Montana to Texas.

Hannah was taken into custody after refusing to obey orders from U.S. Park Police officers, who asked her to move on.

Speaking to Tmz.com before she was whisked away, she said, "Sometimes it's necessary to sacrifice your freedom for a greater freedom. And we want to be free from the horrible death and destruction that fossil fuels cause, and have a clean energy future."

It's not the first time the actress' environmental actions have landed her in trouble - in 2006, Hannah was arrested for camping out in a tree in an attempt to block the bulldozing of a community garden in Los Angeles, and again in 2009 for protesting mountain top mining in West Virginia.
