Sheriff's deputies say a Spanish teacher at a private school was arrested on suspicion of calling in a bomb threat at three private schools in Ouachita Parish.

The News-Star reports that David Reyna, a 30-year-old teacher at River Oaks School, was booked into the Ouachita Correctional Center on Friday after he was arrested by sheriff's office investigators.

He's being held without bond pending a court hearing. He was charged with a count of communicating false information of a planned bombing of school property.

Prosecutors say Reyna poses a danger to the community, "especially the schools and school system," and poses a potential flight risk.

River Oaks School Headmaster Tom Middleton said Reyna was a quiet man on campus, giving no indication of a troubled life.
