A local youth lies on a sidewalk after he was briefly knocked unconscious Thursday afternoon during a fistfight in downtown Salt Lake City. Police were called to 50 S. Main between the Crossroads Plaza and ZCMI Center after receiving reports that two juveniles had been stabbed. Officers later determined that a fistfight broke out about 1:30 p.m. between groups of juveniles that often hang out in the two malls. Only minor injuries were reported.
