Pascack Valley High School is dealing with a series of bias incidents after swastikas were found drawn in bathroom stalls over the last few weeks.
The most recent incident was Tuesday morning when three swastikas were found by staff members.
The areas were closed off to remove the symbols.
School officials are working with the student government on ways to educate students against such acts.
Back in September, a swastika was found in two boys' bathroom stalls at the high school.
