Huntington Beach High School students were sent home while authorities investigated a suspicious box brought to campus today.
Police were sent to the school about 9:40 a.m. after a student brought to campus what appeared to be firecrackers, police Lt. Russell Reinhart said.
When officers arrived, they discovered the student also had a "suspicious box," Reinhart said.
"We decided to err on the side of caution and locked down the school and have the [Orange County sheriff's] bomb squad determine what" the suspicious item was, he said.
The student was being detained at the police department, which is across the street from the school. Police closed down Main Street.
Students were initially sent to the school's parking lot and stadium while authorities investigated the suspicious device. About 11:15 a.m., Principal Janie Hoy sent the students home for the day, Reinhart said.
There were no reports of injuries.
Details about the student who allegedly brought the suspicious items to school were not released.
