GREENBURGH, N.Y. (AP) — An Oregon teenager was questioned Saturday about Internet chat room threats that forced the cancellation of classes in a school district.

The teenager admitted making the threats but told investigators it was an innocent hoax, police said.

Officials in the Edgemont district in Westchester County canceled classes Friday at three schools after a student received an Internet threat about "a lot of bodies" at Edgemont High. The district serves 1,700 students and has 150 staff.

The threat made early Friday morning in an America Online chat room did not specify a method but warned, "There's going to be a lot of bodies around," investigators said. The recipient, an Edgemont High student, quickly called police.

The message was traced to a home in Oregon, and investigators seized a computer from the residence. The teen's identity and hometown were withheld because no charges had been filed.

On Thursday, at a high school in suburban San Diego, Calif., an 18-year-old student was arrested for allegedly opening fire on his classmates and wounding five. The shooting at Granite Hills High School, in El Cajon, came three weeks after a deadly school shooting a few miles away at Santana High School, in Santee, Calif.
