A student at Mountain View High School in Loveland was arrested Thursday, December 5, after bringing a knife to school and threatening another student with it.

The 17-year-old was charged with first-degree attempted assault, felony menacing, unlawfully carrying a weapon on school grounds and unlawfully carrying a concealed weapon, which turned out to be a small pocket knife.

According to the Denver Post:

A 17-year-old male student used a vulgar word in class, which was reported to the teacher by a 16-year-old male student. The reports says the 17-year-old wished to fight the other student after school, but the 16-year-old indicated he didn't want to. While the teacher turned her back to notify the school administration, the 17-year-old took out a weapon and threatened the other student.
