...Amnesty International and the Centre for Environment, Human Rights and Development (CEHRD) have disagreed with the claims by Shell Petroleum Development Company (SPDC) Nigeria Limited that sabotage was responsible for a seven-day-long oil spill in the Niger Delta region in June 2012. The rights groups stated in a report that a recent investigation into the oil spill in the Bodo region was “a fiasco”...The...report...focused on the lack of transparency in the joint investigation carried out by Shell, members of the community and local authorities...[E]xperts who had examined the pipes explained that there are strong indications that the leak was due to corrosion...rather than sabotage...Amnesty and CEHRD had directed a United States firm, Accufacts, with years of experience in examining oil infrastructure, to examine photographs of the pipeline at the leak point.
