5 arrested in high school pyrotechnics

Five recent graduates were arrested in connection with pyrotechnic devices that prompted evacuations at a high school earlier this month, authorities said Wednesday.

Chief Assistant Prosecutor James Wilson said the five males, all ages 17 or 18, were taken into custody Tuesday night and Wednesday morning. He gave no details about their identities nor what charges each might face, pending a news conference Wednesday afternoon.

The devices were found June 13 in two second-floor lockers at Wayne Valley High School after a student noticed fuses hanging from one locker. About 1,400 students were evacuated. It was the day before the start of final exams.

The devices, 5-6 inches long, were removed by a bomb squad and detonated safely. Officials described them as "pyrotechnic devices," but not dynamite or fireworks.

Surveillance tapes showed two hooded people putting the devices into the lockers.
