ARLINGTON, Wash. -- State Fish and Wildlife agents have set a trap for a bear seen walking close to schools and residential areas bordered by woods.

Agents said residents in Arlington should help encourage the black bear to return to its natural habitat by eliminating food sources.

The call for help came after Arlington residents reported new sightings of a reappearing black bear in the Crown Ridge neighborhood Thursday morning.

The bear has been spotted near three area schools, including Arlington High School.

Sgt. Randy Lambert said homeowners in the area should secure bird feeders and garbage cans that are known to attract bears. Lambert said the bear will continue to visit the area as long as a food source exists.

Resident Scott Richardson said he and his son have seen evidence of the bear and a neighbor was able to take photos of the visiting bear in action.

Agents set a trap with sardines, doughnuts and bacon grease in an attempt to trap the animal and take it back into the Cascades.

In the meantime, Arlington school officials warned students not to walk alone to school as a cautionary measure.

Authorities don't believe the black bear poses much of a threat because bears are usually spooked by humans.
