Throughout the day, the man in the tree has thrown an apple, branches, pine cones and various other items at officers. Police say the man's "precarious position" high above the ground endangers himself and others.

KIRO-TV spoke to an employee of King County Community and Human Services, who said someone with a mental health crisis on the streets would likely be brought to Harborview first. One would get a diagnosis there, before being directed to other services.
