Actress Daryl Hannah was arrested by U.S. Park Police yesterday while she was protesting in front of the White House for a pipeline expansion project from Canada to the U.S. Gulf Coast.

There were involved 100 people protesting Trans Canada Corp.'s Keystone XL pipeline which were also arrested. Stretching over 1,600 miles - twice the length of the Trans-Alaska system - the new pipeline would be one of the biggest in the country.

Before the arrest, the "Splash" actress told The Associated Press the protesters want to be free from dependence on fossil fuels. The group calls for clean energy investments instead. Hannah says they hope President Barack Obama will not bow to oil lobbyists.

Hannah sat down on the sidewalk near the White House and refused orders from U.S. Park Police to move.

She has been arrested in the past for environmental causes.
