A man is in custody after a shooting at a market in Southwest Fresno

FRESNO, Calif. (KFSN) -- One suspect is in police custody after a shooting at the Westside Market in Southwest Fresno.

Fresno police say 19-year-old Sir Anthony Robinson was in the parking lot of the market near Elm Avenue and Grove Street when a white vehicle pulled up and began shooting at Robinson's car.

Witnesses told police Robinson then began chasing and shooting at the white car.

Authorities later located Robinson in a burgundy Lexus with the rear window and passenger side windows shot out.

Officials say inside the vehicle was a loaded handgun but before police found Robinson -- officers responded to a different shots fired call from a vehicle in the area of Fresno Street and Kearney Boulevard.

That is where authorities spotted several shell casings in the street.

Authorities have determined the two shootings are not related. However, officials believe the Westside Market shooting is possibly gang-related.
