A man was critically injured early Sunday evening, after a large group of men chased him through Dolores Park then beat and stabbed him in a nearby intersection.

According to the San Francisco Police Department, witnesses say that the 25-year-old victim was seen running through the park at 6:15 p.m. Sunday, with as many as ten men of unknown age in hot pursuit.

The victim, police say, "fell in the middle of the intersection" of 18th and Church Streets. That's when, according to the SFPD report on the incident, the group of men "began punching and kicking" the victim, leaving him with "a stab wound to his upper torso."

The victim was transported to San Francisco General Hospital with wounds police say are life threatening. An update on his condition was not available as of Monday morning.

No arrests have been made in this case, according to the SFPD. Neither information on any possible suspects nor details regarding a motive were provided as of publication time.
