Regulators also investigating whether BP properly disclosed drilling riskshttp://www.msnbc.msn.com/id/38525222/ns/business-us_business/ U.S. securities regulators are probing potential insider trading at BP in the weeks and months following the disastrous Gulf of Mexico oil spill, two sources familiar with the investigation said on Monday.
The Securities and Exchange Commission is also investigating whether BP properly disclosed information on risks related to its deepwater oil operations in the Gulf of Mexico, one of the sources said.
The sources cautioned that the investigation was preliminary and requested anonymity because they were not authorized to speak publicly about the matter.
Last week, BP said the SEC and the Justice Department were conducting "informal inquiries into securities matters arising in relation" to the explosion at an offshore rig that ruptured BP's well.
