Dustin Diamond, who famously played Screech on the sitcom "Saved by the Bell," was arrested early Friday in Wisconsin on charges including recklessly endangering safety in the first degree, a felony.
The actor was taken into custody in Ozaukee County, north of Milwaukee, the county sheriff's department confirmed.
According to the department's website, Diamond was being held in lieu of $1,000 bail on the felony charge as well as two Class A misdemeanors: possession of a switchblade knife and carrying a concealed weapon.
Though a department spokeswoman said more details were not expected to be made public until after the actor's court appearance, scheduled for 1:30 p.m. local time, Gossip Cop reported that the actor and his girlfriend were arrested at home after an alleged bar fight.
Diamond's girlfriend allegedly punched another woman who was antagonizing them, the website said. Diamond defended his girlfriend, the website said, and the two went home.
The former child star, now 37, appeared as the awkward and often annoying Samuel "Screech" Powers on NBC's "Bell" during its 1989-1993 run, with a cast that included Mark-Paul Gosselaar, Mario Lopez, Elizabeth Berkley and Tiffani Thiesssen. He continued for a year with "Saved By the Bell: The College Years" before moving on to "Saved By the Bell: The New Class," which ran from 1994 into 2000. Diamond has appeared as himself in "Celebrity Fit Club" and "Celebrity Big Brother."
