A young man was hospitalized with a brain injury Friday after a mob of 15 to 30 men and women attacked him on a street in San Francisco’s South of Market neighborhood, police said.

The victim, described as being in his early 20s, was beaten at the intersection of Harrison and Harriet streets, near Victoria Manalo Draves Park, about 2:40 a.m., a witness told police.

The man’s attackers punched, kicked and hit him with glass bottles before fleeing on foot, said Officer Grace Gatpandan, a San Francisco Police Department spokeswoman.

The victim was unconscious when officers arrived, said Gatpandan.

The man was rushed to a nearby hospital with life-threatening injuries and deteriorating brain function, but his condition was upgraded to non-life-threatening at the hospital, Gatpandan said.

No one had been arrested as of Friday afternoon.

Police continued canvas the area, looking for surveillance footage of the attack.
