Police say they found a man shot in the leg inside a building under renovation on Belmont Avenue and Fulton Street around 4:50 am.
Investigators say the man was inside when two others came through the back door. An argument erupted, and one of the men pulled out a gun and opened fire at the victim.
The man was taken to Community Regional Medical Center in downtown Fresno with non-life-threatening injuries.
Officers say the other two men ran away after the shooting. Investigators are now canvassing the area in search of the suspects.
