Actor Dustin Diamond, best known for his role as 'Screech,' in the 1990s hit sitcom 'Saved By The Bell,' was arrested and booked into jail in Wisconsin on Wednesday. Officials say he violated the terms of his parole.

Diamond, 39, had recently served a four-month sentence for an altercation at a Wisconsin bar.

He was convicted in June of carrying a concealed weapon and disorderly conduct, both misdemeanors. He was cleared of a felony. He was to start jail during the summer, but a judge put the sentence on hold while Diamond appealed. Diamond withdrew his appeal earlier this year..

Diamond testified he was trying to protect his girlfriend when he pulled out a pocketknife to ward people off and accidentally stabbed a man at the Port Washington bar on Christmas in 2014.

Port Washington is 25 miles north of Milwaukee.
