DES MOINES, Iowa (AP) — Two women with civil disobedience arrest records are claiming they damaged valves and set fire to construction equipment along an oil pipeline that crosses Iowa and three other states.

Jessica Reznicek and Ruby Montoya were arrested for criminal mischief at the Iowa Utilities Board office Monday after damaging a sign outside the agency’s building.

The Des Moines women released a statement before their arrest claiming they burned construction machinery, cut through pipe valves with a torch and set fires with gasoline, rags and tires along the Dakota Access pipeline route.

Both women have been arrested in the past year for protesting the $3.8 billion pipeline crossing North Dakota, South Dakota, Iowa and Illinois. It began operating June 1.

Pipeline owner Energy Transfer Partners did not immediately respond to messages.
