SAN DIEGO --
An apparent bottle bomb detonated inside a Lakeside high school classroom during school hours Tuesday.
According to authorities, the device exploded inside a classroom at El Capitan High School shortly before 3 p.m.
Grossmont Union High School District spokeswoman Catherine Martin told 10News a two-litter bottle containing an unknown substance was placed in a trash can inside the classroom during the school's 7th period.
Santee Fire Department officials and San Diego County sheriff's deputies were summoned to investigate and later determined that a pressurized chemical reaction occurred in what appeared to be a bottle bomb, causing the explosion and setting off school fire alarms.
No students or school staff members were seriously injured, but one student was transported after complaining of ringing in the ears, eye irritation and a headache.
No fires were reported and no evacuations were ordered, but school officials said there was some smoke as a result of the explosion.
The sheriff's Bomb/Arson Unit inspected the area and other parts of the campus and found no other devices.
A hazardous materials team was sent in to determine the safety of the classroom and found no residual chemical that could endanger school staff and students.
School officials said students in the class were asked to provide statements about what happened in the classroom before being released.
All other El Capitan students were dismissed from school as normal, and the sheriff's department confirmed classes will resume as scheduled on Wednesday.
An unidentified student was booked into juvenile hall after an interview with deputies at the Santee station, according to the sheriff's department.
