A 71-year-old man was arrested Friday after Austin police say he pulled a gun on a man on Interstate 35 during a road rage incident, according to an arrest affidavit.

Kenneth Williams has been charged with aggravated assault with a deadly weapon and was being held Saturday at the Travis County Jail on $15,000 bail, online jail records show.

Police said they were called at 11:47 a.m. to the 50 block of Interstate 35 after a caller reported that a person in a black Honda had pointed a gun at him and two other passengers in his vehicle.

When police arrived, they spoke to the victim, who said he had been driving north on I-35 near Lady Bird Lake in bumper to bumper traffic and had noticed that the vehicle in front of him would "wait three of four seconds before moving" as if he was on his phone and not paying attention, the affidavit says.

The victim said this happened several times, and the next time it happened, he honked his horn. He said the honk "was a quick honk, not a long honk," but after it, he saw the man in the Honda throw up his hand and make a gesture, the affidavit says. The victim said the man then opened his door, leaned out of the vehicle and pointed a gun at him, the affidavit says.

The victim said he was afraid for his life and "worried his daughter and new baby wouldn't have a father and that his fiancée would have to raise the baby by herself," the document says. He gave police the license plate number of the vehicle the man was driving, which authorities said they tracked to nearby 15th Street.

Police conducted a traffic stop on the vehicle and took Williams into custody. Officers also located a Ruger 38 revolver in the vehicle, the affidavit says.

According to the document, Williams told police he had been driving on the highway and the vehicle behind him would not "back off." He said he waved the gun in the air but the driver would still not stop tailgating him, the affidavit says. He admitted he stopped the vehicle and yelled at him but said he did not point his weapon at the other driver.
