PHOENIX -- The Valley man accused of causing multiple car accidents and stripping naked in the street has entered a plea in his case.

John Brigham, 45, was in court Thursday where he pleaded not guilty to several charges, including aggravated assault, robbery and DUI. He is due back in court on September 6.

Brigham’s wild afternoon began on June 29 when he got into a car accident at Hayden and Via de Ventura. He allegedly took off all of his clothes and then jumped on top of one of the vehicles involved in the accident and started screaming and chanting.

Brigham went on to force a woman out of her vehicle and started driving it down Shea Boulevard. He caused a second accident when he crossed over into oncoming traffic.

Brigham attempted to enter three other vehicles before he was eventually arrested. Following the incident, a toxicology screening revealed that Brigham had PCP in his system.

A total of seven people were injured during Brigham’s allegedly wild ride around Scottsdale. One of the victims was a pregnant woman who needed surgery after suffering two broken legs.
