Teen charged after violent threats posted in another Cambridge school washroom

The recent string of threats left in restrooms at Cambridge schools continued this week as Waterloo Regional Police said another incident had occurred on Tuesday.

They say officers have been called in Preston High School on Rose Street at 1:15 p.m. after threats of violence against staff and students as well as the school itself were discovered in restrooms and cafeterias.

A day later, police said a teenager had been charged with death threats and mischief under $5,000, in connection with graffiti.

Last week, similar incidents occurred at three different schools in Cambridge: Monsignor Doyle Catholic High School on June 10, as well as Avenue Public Schools and St. Benedict on Thursday.

There were no arrests in any of those cases.
