AMERICAN FORK — An Alpine man was arrested Wednesday after police say he attacked a woman in a road rage incident in which he apparently caused his car to flip over.

Bill Kelsch, 39, rammed his vehicle into another vehicle in American Fork Wednesday afternoon "over a road rage issue," a police affidavit filed in 4th District Court states.

"Bill admitted to being upset with the victim because she flipped him off, so he 'lost it' and swerved purposely into the victim's car and caused his own vehicle to flip over," the affidavit states.

Police say Kelsch and the woman both exited their vehicles and Kelsch ran after the woman. Upon reaching her, he began hitting her "with his fists in her back," according to the affidavit. Multiple witnesses watched the incident and told police that Kelsch was yelling and "acting disorderly."

Kelsch was booked into the Utah County Jail for investigation of aggravated assault, simple assault, aggressive driving and disorderly conduct.
