Two men are in police custody in connection with a brutal daylight attack that left a man in a coma.
Police say 59-year-old Tiansheng Yu and his 27-year-old son, Jin Cheng Yu, were shopping in downtown Oakland on Friday afternoon when two men confronted the son and punched him without warning in an apparent unprovoked attack.
When the father later confronted the men, they allegedly punched the elder Yu, causing him to fall and hit his head on the pavement. He was knocked out cold. Tiansheng Yu is still hospitalized in a coma.
Surveillance video from a nearby store showed the suapects before and after the attack. Officers arrested two 18-year-old suspects early Tuesday morning on suspicion of battery causing great bodily injury. Their names have not been released.
