NIAGARA FALLS - State Parks Police arrested six activists who unfurled a 70-foot banner this morning off the observation deck in Niagara Falls State Park in protest of the use of tar sands oil.

Two men and a woman who rappelled to the bottom of the banner dangled from the observation deck for about five hours before climbing back up to face arrest, said Sgt. James Comfort.

"They were tied onto the banner so the banner couldn't be pulled up," Comfort said.
