Two 16-year-old high school students are in police custody in connection with a small explosion at Hilo High School.
No one was injured in the incident.
At 11:34 a.m., South Hilo patrol officers responded to a report that a device had detonated on campus. When police arrived, the school went into lockdown.
Police recovered the remnants of a plastic liquid container and an unidentified liquid substance. The device was in an open corridor near the school's auditorium. The only damage was residue at the site, according to a Hawaii island police advisory.
Patrol officers and school security guards screened the campus for any additional devices but found none.
The lockdown was lifted shortly before 1 p.m.
Police arrested two 16-year-old boys but detectives are continuing the investigation.
The incident marks the second time this week that a school campus has gone into lockdown, during which students and teachers are locked in their classrooms.
On Tuesday, Roosevelt High School went into lockdown following a shooting on the Punchbowl-area campus.
Police shot and injured a 17-year-old boy in a school counselor's office after he allegedly tried to stab officers trying to take him into custody.
