A chauffeur who says he was attacked by comedian Katt Williams at the Portland International Airport on Friday is suing the entertainer for $76,000, claiming Williams berated, punched and set his German Shepherd on him when he refused to let the dog ride in the passenger's seat.

Wali Kanani is accusing Williams of assault, battery and intentional infliction of emotional distress in the lawsuit filed Monday in Multnomah County Circuit Court. Williams, 47, remains held in the Multnomah County Detention Center as of Monday evening on suspicion of fourth-degree assault.

The stand-up comedian, whose real name is Micah S. Williams, pleaded not guilty to the allegation earlier Monday. Police said he also has an outstanding warrant in Georgia.

During Williams' arraignment, a man who identified himself as the comedian's friend attended the hearing with a German Shepherd wearing a strap that read, "Service Dog". He declined to say if the dog belonged to Williams.

Kanani said in the lawsuit that his encounter with Williams left him with a broken tooth, a cut and swollen face and tinnitus in his ear that caused him to still hear ringing when the suit was filed.

Portland lawyer Stacey Reding, who is listed as Williams' attorney in the criminal case, did not immediately respond to a request for comment Monday.

According to the lawsuit, Kanani claims Williams, six other people and a "large, aggressive German Shepherd," met him at an airport hangar around 11 p.m. after they got off a private jet. Williams insisted the dog ride in the passenger's seat of Kanani's 2017 GMC Yukon XL Denali, the driver said in the suit.

The Port of Portland said Williams was in Portland to attend a live tour performance of Nick Cannon's "Wild 'N Out" improv comedy show. Williams was once a regular cast member of the MTV show. According to an event press release, the show started at 8 p.m. Friday at the Moda Center. Kanani claims Williams arrived to Atlantic Aviation, which handles private plane services at the airport, one hour later than scheduled.

Kanani, 38, said in the lawsuit that when he told Williams he wasn't comfortable with the dog sitting up front and told him the pet would have to ride in the back, Williams called him a "piece of (expletive)" and "white trash" and then punched him in the face.

The lawsuit said Williams and his dog chased Kanani as the driver ran to the airport terminal. Kanani got there first and locked the glass door to keep them away from him, the court papers said.

"(Williams) stood on the other side giving (Kanani) menacing and threatening glares for several minutes before he left in another car that had arrived to take (Williams) and his colleagues away," the lawsuit said. Kanani called 911 and was taken to Legacy Meridian Park Medical Center in Tualatin.

Williams was arrested in Portland on Saturday morning, police said.

In the lawsuit, Kanani said he is entitled to damages because of Williams' "unconscionable acts and his history of tortious behavior."

Williams' criminal history includes being sentenced in April 2017 to three years of probation and a year of anger management in California after pleading no contest to robbery for being part of the snatching of a camera from a photographer three years earlier. He was also sentenced to five years of probation in Georgia in December 2016 after pleading no contest to assault and battery for his role in the beating of his security guard with a baseball bat. He was ordered by a judge at the time to perform community service, surrender guns seized from his home and avoid the bodyguard.

Williams won an Emmy last month stemming from a guest appearance on FX show "Atlanta".
