A Muni patron was rushed to the hospital this weekend, when two fellow riders attacked him seemingly without provocation.

According to the San Francisco Police Department, the assault occurred at 5:22 on Saturday afternoon, as a Muni bus traveled through the intersection at 11th and Market Streets, near the headquarters of Mid-Market startups Square and Uber.

Police say that two male assailants who looked to be aged 16 or 17 "began yelling at" a 17-year-old male who was also on the bus.

The verbal attack turned physical, police say, when the victim tried to get off the bus to escape the yelling men. Instead, the assailants physically "attacked [the victim], knocking him down."

The suspects then fled the bus, police say.

The victim was left injured following the scrum, police say, and was transported to an area hospital for treatment. The suspects remain at large, police say, and no arrests have been made in the case.
