Friday night phone calls reporting gunfire led Menlo Park police to the 1100 block of Willow Road around 10:37 p.m.
There, they found 24-year-old Saul Mendoza, of South San Francisco, who reportedly attempted to run away, according to police. Despite struggling, he was taken into custody. Officers said they also discovered a loaded gun and a "large amount" of marijuana and methamphetamine nearby.
Mr. Mendoza was booked into San Mateo County jail on weapons and narcotics charges as well as battery on a law enforcement officer.
