VIDEO: Brutal beating of bus driver caught on camera

Shocking surveillance video captured the moment an Olympia, Washington transit bus driver gets attacked by a passenger after the two start arguing.

Driver Robert Weigelt told 24-year-old Kiel Duggins to get off the bus because he was tired of him using foul language. He opened the door and order Duggins out.

"If you hit me in the face, we will fight to the death,” Duggins told the driver. Weigelt came inches to Duggins face and then shoved him. Duggins then started beating the driver over and over again.

A passenger tried to step and help but Duggins kept up the attack. Then what he said is even more disturbing.

"You bleeding? Is that real blood? Let me taste it."

Weigelt suffered two black eyes and his nose was broken. Duggins is being held in jail for investigation on a 3rd degree assault charge.
