Three Derby High School students have been arrested in connection with the detonation of pop-bottle bombs that prompted a lockdown of the school Tuesday afternoon.
The boys — two of them 15, one of them 16 — were taken into custody at about 5:30 p.m. Tuesday, Derby Deputy Police Chief Doug Chambers said.
Two of the bombs were detonated in a locker room shortly before 2 p.m., Chambers said, and a third did not explode.
No injuries or structural damage occurred, but the school went into lockdown for about an hour while authorities searched for other devices.
Once the search was completed, classes were released for the day about 15 minutes early, Chambers said. The school returned to its normal schedule Wednesday.
A fourth student was questioned but released when authorities determined he was not involved in the incident, Chambers said.
