Fresno Police are asking for the public's help in finding a serial armed robber.
Investigators say 23-year-old Joseph Dominguez is connected to three separate incidents in central Fresno.
In each case, authorities say Dominguez and a juvenile held victims at gunpoint, assaulted them with their weapons and ran off with stolen property.
In one incident near Shields and Maroa, the victim was knocked unconscious, suffering a broken jaw and brain bleeds.
The juvenile suspect in the case has since been arrested as Dominguez remains on the loose.
If you know anything on his whereabouts, you are asked to call Fresno Police.
