PORTLAND, Ore. -- A Portland bomb squad destroyed a school science project Saturday after they received reports of a suspicious package.

Authorities said a box with a wire and screws sticking out of it was found at the Mittleman Jewish Community Center on Southwest Capitol Highway. A note posted on the box said, "Do not touch."

Police called in a bomb squad as a precaution. The bomb squad then blew up the device, but later learned it was a school science project.

A suspicious package in Woodburn also turned out to be harmless Saturday. Police received reports of an unusually-placed box Saturday morning at the Telecare Recovery Center. Three houses were evacuated before the bomb squad declared the package safe.

The box turned out to be full of packing peanuts, police said.

Two months ago, a bomb at a Woodburn bank killed two police officers and critically injured the town's chief of police. A father and son were later arrested in the case.

Portland Police Detective Mary Wheat said officers "can't be too careful" in light of the fatal Woodburn blast.
