Officers responded at about 5:50 p.m. to the 400 block of Huntington Avenue, where witnesses reported seeing a group of roughly eight people involved in a fight, police said.
A 16-year-old South San Francisco boy was stabbed during the physical altercation. He was transported to a local hospital for treatment, and police said he is expected to recover from those injuries.
