Fifteen students and eight adults were showered by a fire hose and a central Ohio high school's music building was locked down after a suspicious package was delivered to the band room.

And it was all a false alarm.

A hazardous materials unit was sent to Newark High School Friday after it was reported that an envelope containing white powder had been delivered to a band director. The director and a secretary both complained of itching.

But Licking County Emergency Management Agency Director Jeff Walker says there never was any powder. He says the envelope held a photocopy of a textbook page on World War I.

U.S. Postal Inspector Alejandro Almaguer says there was a miscommunication.

The people in the building were quarantined and eventually given decontamination showers outdoors.
