North Dakota pipeline protest prompts more than 80 arrests

More than 80 people protesting the Dakota Access pipeline were arrested Saturday during a demonstration that gathered about 300 people at a construction site in North Dakota.

The confrontation between officers and protestors near the confluence of the Missouri and Cannonball rivers lasted five hours.

Officers used pepper spray when some protestors attempted to breach a line set up between demonstrators and construction equipment.

Texas-based Energy Transfer Partners is trying to finish construction of the 1,200-mile pipeline. Some 220 people now have been arrested since demonstrations began in August.
