Within a half hour of arriving on site to clean up Bhopal, around 60 protesters including local residents and Greenpeace activists were arrested. It was estimated that more than 100 police in riot gear swarmed over the peaceful action, which was taking place at the former Union Carbide factory, now owned by Dow, where a deadly gas leak in 1984 killed thousands and blinded and maimed thousands more. Former Union Carbide CEO Warren Anderson has been wanted for culpable homicide for more than a decade for his role in the accident.
