BRAMPTON, Ont. – Nine students at a Brampton high school were disciplined Thursday for posting offensive comments about their teachers on Twitter.

The group of students at St. Marguerite d’Youville Secondary School were told not to come to school Wednesday after Peel police were made aware of the tweets.

On Thursday, the students were disciplined for the comments, including some that were sexual in nature.

“Nobody has the right to malign anybody,” Bruce Campbell, director of communications for the Dufferin-Peel Catholic School Board told CityNews Channel.

Two students received seven-day suspensions, must write an apology letter and were removed from the classes taught by the teachers they posted comments about.

Three students were suspended for two days and must write an apology letter.

Two of the students were asked to stay home Wednesday and must also write an apology letter.

The remaining two students, whose involvement was deemed minor, were given a warning.

No charges were laid.

Campbell said he hopes the students understand the responsibility involved when using social media.

“The words that you put out there on social media, they don’t suddenly disappear, they’re out there, everybody gets to see them,” he said.
