Authorities say Alexander Lien was chased by bikers after he initially bumped one during a biker rally on September 29. When his SUV was surrounded by several bikers, Lien called 9-1-1, told police he feared for his life and drove off, running over bikers and critically injuring one.

Lien's wife and 2-year-old daughter were in the vehicle with him. Lien has not been charged.

The chase that followed ended in traffic. Police say Lien's windows were smashed; he was dragged out of the SUV and beaten. He was treated and released from a hospital.

Prosecutors say Braszczok is on video allegedly using his fist to bash in the rear window of Lien's SUV and kick it.
