WAILUKU, Hawaii (AP) --Graffiti found at Lahainaluna High School in Wailuku, Hawaii, has been classified terroristic threatening, as well as misdemeanor criminal property damage, Maui police said.
The graffiti led about 700 of the school's 1,050 students to stay away from classes Wednesday.
The graffiti found in three boys' restroom on Oct. 8 and Oct. 15 made a reference to Wednesday, Principal Michael Nakano.
Parents were given the choice of sending their children to school Wednesday, or keeping them home, Nakano said.
There was no incident at the school Wednesday, and most students attended classes Thursday, he said.
Sgt. Hervina Santos declined to reveal what the graffiti said, but called it ``offensive in nature.''
"It was quite disturbing, and we are taking this matter seriously,'' Nakano wrote to parents and guardians in an Oct. 14 letter.
