TWIN RIVERS, Calif. (AP) - A substitute teacher in Northern California is under investigation following accusations that he was watching pornography at an elementary school.

The Sacramento Bee reports that a junior high school-age student at Orchard Elementary School in Rio Linda reported seeing a nude person on the male substitute teacher's computer screen earlier this week.

His name has not been released.

Twin Rivers Unified School District Assistant Superintendent Tom Janis says parents have been notified and the substitute teacher has been banned from their campuses until the investigation is completed.

Janis declined to discuss the incident or the teacher's history with the district citing the ongoing investigation.

Janis says while the teacher can still work in other districts, they will notify those other districts if the allegation turns out to be true.
