A Nanaimo teacher whose guilty plea to uttering threats sparked a security scare at local schools has been temporarily banned from teaching in B.C., the province’s Teachers' Regulation Branch says.

Francies Willem Van Der Voort Maarschalk was suspended from teaching in Nanaimo last September, when the allegations of uttering threats were first reported.

After Van Der Voort Maarschalk pleaded guilty to the charge of uttering threats to cause death or bodily harm last Tuesday, the school district posted security guards at three Nanaimo schools and the district office where the teacher had worked.

Van Der Voort Maarschalk was sentenced to one day in jail and 18 months probation, and was given a five-year ban on owning any firearms.

B.C.'s Teachers Regulation Commissioner has posted a citation on line, saying Van Der Voort Maarschalk is not eligible to practise teaching in any school district in the province, pending the outcome of a future certification hearing.

Commissioner Bruce Preston says the public will have access to more information about the case on the Commission’s website in the future.

"More details of that citation will be given fairly close to the hearing so that any member of the public who wants to attend the hearing can take a look at that and decide whether they want to attend the hearing."

The hearing will be conducted by a three-member panel which will decide whether to suspend or permanently cancel Van Der Voort Maarschalk's teaching certificate.
