A month after ending a three-month jail sentence, actor Dustin Diamond (Screech on Saved by the Bell) is back in the slammer.

.

There's very little available information other than this being a probation hold enacted in Port Washington, Wisc. CNN says this type of arrest happens "when the offender's probation agent believes he or she has not complied with the terms of their probation."

.

Diamond, now 39, stabbed a man in a Wisconsin bar on Christmas Day 2014. On April 11, 2016, he was released after three months of a four-month sentence.

Next up will be an investigation of the violation. It could result in a revocation of Diamond's parole. "No new charges have been filed against Diamond," CNN writes, "and no other information is available at this time, according to the jail."
