The victim then is seen lying motionless after the attack as the suspect casually walks away into United Nations’ Plaza. The victim suffered serious injuries requiring hospitalization.

During the Muni bus assault, a suspect approached the victim, yelled at him, grabbed the victim by his hair and repeatedly slammed the victim’s face into a steel handrail leaving the victim with severe injuries including a broken nose.

This incident was also captured on Muni surveillance video.
