The North Dakota Education Standards and Practices Board has revoked the license of a former police officer and substitute teacher in Williston.
Bryton Dahl was convicted of felony corruption or solicitation of a minor in November for having a sexual relationship with a 16-year-old boy he met online.
Last month, he was sentenced to three years in prison with all but the 123 days he spent in jail awaiting sentencing suspended.
Dahl is a former officer of the Williston Police Department and the McKenzie County Sheriff's Office. He also worked as a substitute teacher at Williston Public School District No. 1.
Under state law, the North Dakota Education Standards and Practices Board is required to "immediately revoke the teaching license of an individual who has been found guilty of a crime against a child or a sexual offense."
On Thursday, the board voted unanimously to revoke Dahl's license.
