Coast Guard officials in New Orleans say a petty officer has been convicted and sentenced on charges involving sexual assault and possession of child pornography.

Petty Officer 2nd Class Christopher C. Bush's court martial was held in Norfolk, Va.

A Coast Guard news release said the 28-year-old Bush was convicted Friday on four violations of a Uniform Code of Military Justice article dealing with rape and sexual assault and one involving child pornography.

The crimes involved a junior Coast Guard woman and a civilian woman. They happened between January 2010 and May 2013 while Bush was stationed at a unit in New Orleans. The Coast Guard said it was not releasing the name of the unit to protect the privacy of the victims.
