(Portland, OR)  --  A tense situation is over after a man climbed down from a construction crane in Portland after being on top of it for hours.  Some people spread messages of love on the street after he climbed a construction crane and refused to come down yesterday.  The signs hundreds of feet below him read "We love you"  and "You matter."  Police responded to calls at 1 p.m. and said the man is known to police and he may have mental health issues.  Police used a megaphone to urge the man to climb down.  After about five hours he finally began to return to the ground.
