Dustin Diamond could face up to 10 months in prison.

The 'Saved By The Bell' actor was found guilty of carrying a concealed weapon and disorderly conduct yesterday (29.05.15), after being involved in a bar brawl last Christmas Day, but was cleared of a felony charge of recklessly endangering public safety.

Carrying a weapon carries a maximum sentence of nine months in prison, while disorderly conduct is 90 days.

According to Australian website News.com.au, witnesses testified that Dustin's girlfriend Amanda Schutz - who also faces a misdemeanour disorderly conduct charge - pushed one woman at the bar on Christmas Day and grabbed another woman's hand, initiating the incident.

Dustin said he tried to help Amanda and took out his pocketknife to deter the group from hurting her more.

However, Ozaukee County District Lawyer Adam Gerol argued yesterday (29.05.15) that the 38-year-old former 'Celebrity Big Brother' housemate lied about what happened and that he had scripted his testimony.

Mr Gerol showed body-camera footage of Dustin's testimony to a police officer the night of the fight. In the video the actor first said he might have struck Casey Smet with a pen, but later that night, said he had a knife at the bar, but hadn't used it to stab anyone.

Dustin - who is famous for playing Screech in 'Saved By The Bell' - didn't display any emotion when the jury revealed their decision and told reporters that he couldn't comment as he left the court,

A sentencing date for Dustin and Amanda has not been announced.
