Former Saved by the Bell actor and Celebrity Big Brother star Dustin Diamond has begun a four-month sentence for an altercation at a bar in Wisconsin in the United States.
The Ozaukee County Jail website shows that Diamond arrived at the prison on Friday.
Diamond starred as Screech on the 1990s kids TV show and hit the headlines once again in 2013 when he entered the UK Celebrity Big Brother house – he was evicted after 16 days.
Diamond was convicted in June 2015 of two misdemeanours: carrying a concealed weapon and disorderly conduct.
He was due to start his jail-time during the summer, but a judge put the sentence on hold while Dustin appealed. He withdrew his appeal last month.
Dustin testified he was trying to protect his girlfriend when he pulled out a pocketknife to ward off attackers and accidentally stabbed a man at the Port Washington bar, near Milwaukee, on Christmas day in 2014.
