Zamir Nathoo, 34, a former student engineering student at the University of Waterloo has pleaded guilty to criminal harassment for a series of threatening messages at the school last year.

The Kitchener man was sentenced to eight months, the time he has already spent in custody, plus two years probation.

Shannon Dea, a philosophy professor at the university, testified at the two-day trial.

"It's been a very stressful year, at points very frightening. I think we'll all sleep easier knowing Mr. Nathoo is getting the help that he needs and that ultimately the police and the university really were concerned with our safety," she says.

Dea was among those who received numerous threatening emails and attachments that included anti-feminist, anti-semitic and strong political messages.

Some messages sent out fraudulently purported to be from the university's president.

Posters were also put up around campus with an image of scientist Marie Curie with text that read "THE TRUTH. The brightest Woman this Earth ever created was Marie Curie, The mother of the Nuclear Bomb. You tell me if the plan of Women leading Men is still a good idea."

The joint investigation between the Waterloo Regional Police Service and University of Waterloo Police began in February 2011 after the emails and posters began circulating on campus.

There were reports similar literature was sent to Wilfrid Laurier University and the Balsillie School of Business.
