"Saved by the Bell" actor Dustin Diamond posts bail

Dustin Diamond, the actor who played Screech in the 1990s television show "Saved by the Bell," has appeared in a Wisconsin courtroom.

Diamond is accused of stabbing a man during a bar fight on Christmas in Port Washington, where he lives. A criminal complaint charges Diamond with second-degree recklessly endangering safety, disorderly conduct and carrying a concealed weapon.

Diamond posted $10,000 bail before his hearing Monday in Ozaukee County Circuit Court.

Defense attorney Thomas Alberti requested reduced bail and a jury trial for Diamond, who did not speak in court.

The complaint says Diamond and his fiancee got into a tussle with two men and a woman at the bar on Thursday night.
