The passenger of the car got out and ran from police.
Officers caught up with him in the backyard of a vacant home. Officers later found a loaded weapon in a bag he tried hiding in the yard.
"You have an armed gang member running with a loaded firearm in a neighborhood you have children, women going about their daily activities. It creates a dangerous situation for all the citizens of Fresno," said Fresno Police Lt. Andre Benson.
After officers made a quick record check, it turns out that weapon was stolen from someone in Oakland.
The suspect arrested Saturday has several active felony arrest warrants.
"He will be booked on charges related to that firearms possession," said Benson.
It's just the latest in an uptick in activity for Fresno police's Multi-Agency Gang Enforcement Consortium or MAGEC.
Since August 5th, detectives and MAGEC teams have combined to make 282 felony arrests, seize 162 guns, and serve 49 search warrants.
Over just the past ten days, they've made 16 felony arrests of known gang members.
"We recovered 12 firearms, three of them assault rifles. What we're seeing now is a lot of gang members are armed with firearms," said Benson.
Lt. Benson says they've been busy and their extra effort is working.
"Our efforts are being successful. We are seeing a slight decrease in the shootings in Fresno."
Benson says making residential neighborhoods safer is a top priority.
"The last thing we want is for some child to pick that handgun up and harm themselves," he says.
