OAK PARK, Ill. — Swastika graffiti has been removed from the lobby of Oak Park-River Forest High School
A parent discovered the swastika on a window sill last week.
School officials say they don’t know who did it.
In a letter to parents, the school superintendent condemned the drawing, saying hate has no place at the school.
Earlier in the year, around 10 Jewish centers in the city received bomb threats.
