A Chowchilla student was arrested on Tuesday morning, accused of making threats to harm high school students, the Chowchilla Police Department reported.
It was similar to the threat a 15-year-old student made Monday night about Larkin High School in Elgin. "After examining the device, bomb squad members indicted that if it had detonated, the device had the potential to cause significant injury or death".
Someone had shredded the American flag that normally graced Hurricane High School's premises and replaced it with an ISIS-like flag.
As students were returning to Hale High School, several reported what was described as gunshots from an apartment complex across the street from the school.
The student also received a criminal summons from the Colorado Springs Police Department.
The suspect has been charged with manufacturing and attempted use of a weapon of mass destruction. Hurricane City Police confirmed that the boy was a suspect in raising the Islamic State flag and that charges will be forthcoming.
After obtaining a search warrant, police found materials in the teen's home matching those found in the bomb.
A Merced College student surrendered to police on February 25 after making unspecified threats on social media, police said, though his post mentioned the college.
The school was evacuated and the student was later arrested. On Tuesday the Modesto police were looking into a threat made on a nationwide crisis line involving Mark Twain Junior High School. As a result, police decided there is no immediate threat to staff and students and the Renfrew County District School Board is proceeding with their regular school day. Police declined to identify the arrested teen or give his age.
"By the end of (lunch), when the fourth period had started, then they evacuated us-which kind of anxious me because it took them the entire lunch period to evacuate all the students for something unsafe in the building", he said.
