Christopher Cruz now faces four felony charges for the Sept. 29th incident. Cruz was free on $1500 bail, but on Wednesday a judge increased it to $20,000.
He was originally charged with a misdemeanor for allegedly cutting off the SUV on the West Side Highway.
Prosecutors say his actions, slowing down in front of the vehicle and causing a fender-bender, set the frenzy in motion that led to driver Alexian Lien getting pulled from his SUV and beaten.
Cruz now faces charges of assault, criminal mischief, riot and coercion. His attorney says the family is working to post the new bond.
Four other bikers were also in court Wednesday.
