A passer-by called police about 11:45 p.m. and said he witnessed three men attacking the man near Stockton and Bush streets. When police arrived, they found the victim on the ground unconscious and bleeding from the ears. He was hospitalized in critical condition.
The previous incident happened in September when a 43-year-old Fremont man was assaulted in the Union Square area. Manuel Gallegos later died from his injuries, and there have been no arrests in the case.
