Royal Dutch Shell's huge oil-drilling rig, the Polar Pioneer, was towed out of Seattle early Monday despite a blockade by a kayak flotilla that attempted to keep it from leaving for the Arctic.
According to the the U.S Coast Guard, 24 protesters were detained after they violated the established "safety zone" around the giant, Alaska-bound oil drilling rig.
The two-dozen detainees, who were only a portion of the large contingent of protesters, were released after receiving civil "notices of violation" that can include a $500 fine but don't carry criminal penalties.
