The New Orleans police department is going to investigate some of its own officers.
A spokesman says the department is looking into whether officers took part in looting after Hurricane Katrina.
News reports put officers at the scene of some of the heaviest looting. Witnesses who said they saw police take items from shelves included a Times Picayune newspaper reporter.
The spokesman says perhaps 12 officers were involved in "misconduct." He did not use the term "looting."
He says authorities are investigating what he calls "the possibility of appropriation of non-essential items" from businesses.
Earlier this week, the city's police superintendent resigned. This, as the looting reports gained more support, and there was intense questioning of earlier police claims of widespread violence after the storm.
