WTF! KATT WILLIAMS QUESTIONED ABOUT SHOPLIFTING IN BEST BUY!

More legal drama for Katt Williams ... TMZ has learned the comic and a female companion were questioned by police in Ohio today over an alleged shoplifting incident at a Best Buy store ... but this time, Katt was NOT arrested.

Law enforcement sources tells TMZ ... cops were dispatched to the Best Buy in Coleraine, OH after receiving a call about a person, who appeared to be in Katt's crew, pocketing several items off the shelves.

Once police arrived to the scene, we're told cops questioned Katt, his female friend and other suspected posse members.

We're told .... after a brief investigation, Katt was NOT arrested -- neither was the woman -- but someone in the group was cited for a "minor misdemeanor."

Katt has a long, storied history with cops -- earlier this year he was arrested after a standoff with a tractor driver ... and before that, he faced off with the boys in blue in Beverly Hills after getting into a shouting match with another dude.

A rep for Katt had no comment.
