Nine to 10 swastikas were written on Roseville high school’s campus.

The Roseville Joint Union High School District Superintendent Ron Severson said the graffiti was discovered Thursday night.

Severson said they were drawn with a small felt pen and that the maintenance crew cleaned it all up.

Since school was out for Veterans Day on Friday, Severson said they will investigate who's responsible on Monday.

He added that this kind of graffiti is rarely found on their campuses.

“We have no tolerance for this type of behavior at Roseville or any of our campuses,” Severson said.
