The Louisiana Attorney General's Office on Thursday announced the arrest of a teacher at Isidore Newman School in New Orleans.
Investigators say 49-year-old Benoit Cransac faces 22 counts of possession of child sexual abuse material.
The attorney general's office says its cyber crimes unit determined Cransac was the owner of an online account that had received the images.
Louisiana Bureau of Investigation agent arrested Cransac on campus.
""If you possess child sexual abuse material, you will be arrested and prosecuted. While this is still an ongoing investigation, anyone with potential information should contact my office at 225-326-6100," said Attorney General Liz Murrill.
