A European probe into possible oil price manipulation expanded with the investigation of a small niche trading house in the Netherlands and a key U.S. senator on Friday called for the Justice Department to join the investigation.
Dutch trading house Argos Energies, a mid-sized trading company that deals in physical oil products and owns storage facilities, was visited by inspectors from the European Commission on Tuesday, a source familiar with the investigation said on Friday.
