A weeks-long San Francisco police investigation that involved a drone overhead and plainclothes officers in the crowd ended over the weekend with the arrest of three people accused of running a coordinated pickpocket crew in Chinatown. Officers recovered stolen items on the street and later served a search warrant that yielded additional evidence. Authorities identified the suspects as Vallejo residents Stefan Ruset, 35, Marian Constantine, 30, and Florin Matei, 26.
Police Tracked a Vehicle Into Chinatown
According to the San Francisco Police Department, detectives working with Central Station and the department's Real Time Investigation Center used automated license plate readers and a police drone last Saturday to track a suspect vehicle into Chinatown. Investigators say plainclothes officers then watched as the group allegedly operated as a team, with one person removing items while others acted as lookouts, before arresting all three without incident. Police say officers recovered stolen property at the scene and returned items to victims during the operation.
Video of the surveillance and arrests has been circulated by local outlets and by police, showing distraction tactics and fast grabs from backpacks and purses. As reported by CBS News Bay Area, the department posted a clip on its Vimeo account that captures both the method and the takedown. Police said tips from Chinatown merchants and residents were key in narrowing the investigation.
Real-Time Tools Helped Investigators Close the Case
San Francisco’s Real-Time Investigation Center, known as RTIC, combines live camera feeds, license-plate readers and drone support to give officers quicker situational awareness during field operations. City materials describe RTIC’s role in coordinating drones, automated license-plate readers and other monitoring tools that investigators have used in recent cases. For background on the program and its expansion, see SF.gov.
Public dashboards that aggregate SFPD incident reports show multiple larceny-theft and pickpocket entries in the Chinatown neighborhood in April and May, which matches the time frame authorities say led to this focused effort. Mapping sites and neighborhood crime reports list several pickpocket complaints filed with the department in mid-April, a pattern that police said prompted added patrols and plainclothes work. Recent entries can be found in local incident tallies at Safemap.
Search Warrant Turned Up Cash and Evidence
Authorities said a search warrant executed at the suspects’ Vallejo residence on May 17 uncovered additional stolen property, clothing that matched what the suspects were seen wearing and more than $14,000 in U.S. currency. The three were booked into the San Francisco County Jail on charges that include grand theft, conspiracy and possession of stolen property, according to the San Francisco Police Department. Officials said the investigation remains active as detectives work to connect recovered items to more victims, including a case from 2024.
Police asked anyone with information to call 415-575-4444 or text TIP411, beginning the message with "SFPD," a tip line highlighted in local coverage of the arrests. As CBS News Bay Area noted, investigators are urging merchants and witnesses who may have video or receipts to come forward to help identify additional victims. Prosecutors are expected to review the case as investigators continue to compile evidence for possible filings.
