Katt Williams is officially a wanted man ... because a Seattle judge just issued a warrant for the comedian's arrest.
Katt didn't show for his arraignment today on assault, harassment, and obstruction charges stemming from his bar fight in Seattle on December 2nd.
TMZ broke the story ... Katt was arrested following the fight, during which he allegedly threatened a bar manager with a pool cue ... and threw a cigarette at a woman.
A rep for the Washington State Attorney's office says Katt’s attorney was there, and claimed his client didn't attend due to a “medical issue."
That excuse didn't fly with the judge ... who immediately issued the bench warrant.
