No, this isn't a repeat -- Katt Williams has been arrested again.

Katt was picked up in L.A. last night (Tuesday) in L.A. on a bench warrant, for blowing off a court date in Sacramento, California. That hearing was an arraignment for his arrest after taking cops on that wild chase while riding a three-wheeled motorcycle.

Officers apparently arrested Katt outside his home. He's said to be fully cooperating and was being held on $100,500 bail.


6:14 AM PT -- Katt was released from custody late last night -- and on his way out of jail, he explained the situation to TMZ.

According to Katt, he was only arrested because he couldn't be in two courtrooms at once ... and chose the case that was more important to him -- the case involving the custody of his children.

But when asked if the judge awarded him custody of his children, Katt explained, "No, I actually don't [have custody] ... the lady who tried to take 'em and lost in court twice, they gave 'em to her."
