ARLINGTON – Arlington police are investigating possible human remains discovered Thursday in a wooded area in the Gleneagle neighborhood.

Officers were alerted to the find early Thursday afternoon when kids playing in the woods on paths behind some homes happened upon the bones, and notified adults, city spokeswoman Kristin Banfield said.

Police cordoned off a cul de sac while detectives processed the scene with help from the Washington State Patrol.

Police said there is no immediate threat to public safety.
