“Saved by the Bell” actor Dustin Diamond was arrested and charged Friday for allegedly stabbing a man after an altercation at a Wisconsin bar, according to media reports. The 37-year-old from Port Washington has been charged with felony second-degree recklessly endangering safety, disorderly conduct and for carrying a concealed weapon.

The star, who played Screech Powers in the 1990s hit sitcom, was with his girlfriend Amanda Schutz when the incident took place Thursday. According to a criminal complaint, which referred to Diamond’s girlfriend as his fiancée, the couple was involved in a fight with two men and a woman, The Associated Press (AP) reported.

The complaint also reportedly said that local police found a switchblade in Diamond’s car and that its point was covered in what appeared to be blood. Diamond later admitted to police that he had accidentally stabbed a man while trying to defend his fiancée, AP reported, citing the complaint.

Diamond told police that "there was a group of intoxicated people being rude and insulting," ABC News reported. According to court documents, the man suffered a half-inch wound with “substantial bleeding,” but his injuries were not life-threatening.  

Diamond is reportedly being held at a bail of $10,000 and a hearing date is scheduled for Dec. 29. Schutz is also reportedly facing a disorderly conduct charge.
