A Redwood City man already facing stalking and restraining-order charges allegedly called his ex-partner more than 400 times and drove back to her home within hours of posting bail, according to police, who arrested him again Monday during a high-risk stop with an unserialized handgun in his car.
Rudy Fidel Avila Naranjo, 34, was arrested for the second time in ten days after Redwood City police say he repeatedly violated a domestic violence restraining order protecting a former dating partner. According to a statement from Redwood City Police
, the investigation began earlier this month when officers learned Avila Naranjo had been driving near the victim's residence and calling her more than 75 times in violation of a protective order.
A Chase, a Drone, and a First Arrest
A Chase, a Drone, and a First Arrest When officers first tried to contact Avila Naranjo on September 5, he fled at a high rate of speed, police say. Officers took him into custody after he attempted to run on foot, according to police. Redwood City uses police drones, according to the department. That aerial program, built on a five-year, $3.7 million contract expansion with Axon Enterprise approved by the Redwood City Council in April 2026, flew more than 1,700 missions across 608 incidents in just the first seven months of 2025, Hoodline has previously reported.
Avila Naranjo posted bond and was released during the early morning hours of September 6, according to police. Officers say that within hours of his release, he called the victim more than 400 additional times and traveled to her residence again — a return trip investigators say came in direct violation of the same restraining order he had just been arrested for breaking.
Prior Allegations Surface as Investigation Widens
As the case developed, investigators say they learned of additional allegations involving prior sexual assaults, criminal threats, and unlawful entry into the victim's residence. Police describe those allegations as part of the ongoing investigation, without specifying further detail or timeline.
The pattern police describe — hundreds of calls and repeated appearances at a victim's home despite a court order — mirrors national findings on intimate partner stalking. The linked source reports that 87% of restraining orders issued against stalkers were later violated by the person they were meant to restrain.
License Plate Readers Trace the Suspect's Vehicle
License Plate Readers Trace the Suspect's Vehicle Police have described using license plate readers as they worked to track movements, according to police. That capability is part of a broader $3.38 million contract the San Mateo County Board of Supervisors approved in January 2026 with Peregrine Technologies, which integrates real-time dispatch, jail records, drone feeds, and license plate data across 16 police departments countywide, as reported by Coastside Buzz.
On September 14, officers conducted a high-risk vehicle stop in the 200 block of Lincoln Avenue and took him into custody without incident, according to the department. Police also reported that his vehicle contained an unserialized handgun and ammunition.
Ghost Gun Adds to Growing Charge List
The discovery of an untraceable firearm carries its own legal weight in California. Assembly Bill 1621, enacted in 2022 and fully effective the following year, imposed broad restrictions on the sale, transfer, and manufacture of unserialized firearms and on certain unfinished precursor parts statewide, according to the Giffords Law Center.
Avila Naranjo was associated with the Maguire Correctional Facility. The allegations include violating a restraining order, stalking, possessing a concealed firearm, and committing a new felony while released on bail.
What the Bail Enhancement Charge Means
What the Bail Enhancement Charge Means The case includes an allegation that a new felony was committed while Avila Naranjo was released on bail. Stalking and protective-order violations are among the allegations described by police.
Police describe the case as involving restraining-order violations, threats, and firearm allegations. Redwood City police say the investigation remains ongoing and that additional charges may be sought.
