Police in Brazil said they have identified a Greek-controlled ship as the source of a huge oil spill off the country's northeastern coast in September. They have issued two search-and-seizure warrants targeting the Rio de Janeiro representatives of the unidentified Greek owner of the vessel. The spill is being treated as a criminal case under Brazil’s environmental law. The spill is believed to have taken place 700km out at sea between July 28 and 29 after the vessel stopped in Venezuela. The spill has impacted 250 beaches, with 2,000 tonnes of sludge collected so far.
