North Dakota teacher accused of having sex with student

OBERON, N.D. -- A principal and his son, a teacher, are no longer employed at a Benson County school after an investigation found the teacher has had a sexual relationship with a student.

Corey Ploium, a former fifth- and sixth-grade teacher in Oberon, has been issued a restraining order to stay away from the school, according to Linda Madson, Oberon School Board president. Lawyers for the district say Ploium refused to cooperate with investigators, but shortly after the investigation started, he submitted his resignation to the school.

School board officials also said the school's principal and Ploium's father, Kenny Ploium, was fired in connection with the claims of sexual abuse, but did not elaborate how he is connected to the investigation.

The investigation was commissioned by attorneys for the school. More specific details, including the age of the student involved in the allegations, were not available, but Oberon School District lawyer Amy De Kok said the investigation "determined that the allegations that he was investigating were substantiated."

No criminal charges have yet been filed. Madson said the board plans to forward the information from the investigation to authorities. She said she wants to ensure the future safety of Oberon students.

"It should be a safe place to be, and we hope whoever was here will come back and whoever's interested will come back," Madson said.

Corey Ploium did not respond to multiple calls asking for comment.

Oberon is a town of 105 people about 25 miles southwest of Devils Lake.
