Dustin Diamond, Who Played Screech on 'Saved by the Bell,' Booked in Wisconsin Jail Dustin Diamond was sentenced to four months in a Wisconsin jail.

 -- Former "Saved by the Bell" actor Dustin Diamond was booked into a Wisconsin jail to serve his four-month sentence in connection to a December 2014 stabbing incident at a bar in the state.

Diamond, 39, was booked Friday into the Ozaukee County jail. He was found guilty of carrying a concealed weapon and disorderly conduct after a three-day trial in June. He was acquitted of a felony.

Diamond initially appealed his conviction, but withdrew it last month.

The actor, best known for playing Screech on "Saved by the Bell," allegedly stabbed a 25-year-old man in a Port Washington bar on Christmas Day, according to a police report.

During the trial, Diamond testified his girlfriend, Amanda Schutz, was involved in an incident with a small group and that he was just trying to protect her. Schutz was found guilty of disorderly conduct.

Diamond admitted he had a pocket knife, but said he only showed it to people at the bar, hoping to scare them off.
