A Palo Alto High School student was taken into custody after writing that they intended to “shoot up” the school during finals week.
According to the Palo Alto Police Department, the incident happened on Tuesday, causing a shelter-in-place.
Police were called to the school around 8:57 a.m. when a teacher arrived and found a threat of violence taped to the classroom’s front door.
“The threat indicated that the person who left the note intended to ‘shoot up’ the classroom later that morning,” PAPD said.
Police learned that a final exam was scheduled that morning in the classroom where the note was posted.
A shelter-in-place was kept in effect until 10:30 a.m. as a precaution. For the next two days, school officials and police worked to identify a suspect.
Then on Thursday afternoon, a 17-year-old male student was pointed as the suspect. He was arrested for criminal threats and released to his family members.
Police said there was no evidence that the boy had a firearm. He is not publicly identified due to his age.
