New Brunswick police say that a 29-year-old woman who enrolled herself at New Brunswick High School and posed as a teenager was not trying to bring harm or violence to the students or faculty.

Hyejeong Shin was charged with one count of providing a false government document to the New Brunswick Board of Education.

Shin was charged on Jan. 24 after posing as a student for several days at the school. The incident led students to stage a protest, declaring that the district wasn’t doing enough to ensure their safety.

Police say that it is not currently known why Shin enrolled herself at the school.
