Operation Gang of Thrones

San Jose, CA - Since March of 2016, detectives of the San Jose Police Department's (SJPD) Gang Investigations Unit began building a criminal conspiracy investigation against a Vietnamese criminal street gang. SJPD worked closely with the Santa Clara County District Attorney's Office, Drug Enforcement Administration, and Federal Bureau of Investigation.

On Tuesday, August 23, 2016, all the agencies mentioned above, as well as personnel from the Santa Clara County Sheriff's Office, Milpitas Police Department, Santa Clara Police Department, Orange County Sheriff's Office, and the Louisiana State Police, served search warrants and arrest warrants at various locations in the cities of San Jose, Santa Clara, Milpitas, Fremont, Anaheim, and an undisclosed location in the State of Louisiana.

This collaborative investigation resulted in the arrest of 23 suspects who are known members or associates of a criminal street gang in San Jose. The suspects were booked into the Santa Clara County Jail on charges ranging from extortion, public corruption, narcotic trafficking, assault, illegal gun possession, and conspiracy. Two of the suspects were arrested in Anaheim, California, by the Orange County Sheriff's Office. There are 6 suspects at large for various felonies, including; Conspiracy, Accessory After the Fact, Narcotics and Gambling.

A total of 34 search warrants were served during this investigation in California and 1 Louisiana. The following evidence was seized:

  • 5 handguns
  • 69 illegal gambling machines
  • Over $200,000 in US Currency
  • Body armor, jewelry, phones, computers, and financial records
  • Investigators also recovered over 4000 Ecstasy pills, 300 Xanax pills, 200 Molly tablets, illegal steroids, over 600 pounds of Marijuana (420 lbs of which was seized by the Louisiana State Police in transit from San Jose)
  • Several vehicles were also seized; which included one with a hidden compartment containing $100,000
  • One alligator

During the course of the investigation, SJPD was alerted to the possible criminal involvement of a San Jose Police Officer. Upon learning this information, SJPD took immediate action by implementing extraordinary investigative measures to determine the extent of the officer's involvement in this criminal investigation.

The investigation revealed that SJPD Officer Derrick Antonio, a 9 1/2 year veteran, was providing confidential law enforcement information to members of a criminal street gang in San Jose. The Santa Clara County District Attorney's Office reviewed the investigation and issued warrants for Officer Antonio's arrest, charging him with 5 felony counts of 502(C)(3) PC - Unauthorized Computer Access and 1 felony count of 32 PC - Accessory After the Fact.

On 8-23-16, Officer Antonio was arrested in the City of San Jose by members of the SJPD's Criminal Investigations Detail. He was booked into the Santa Clara County Jail on the above charges. Officer Antonio has been on paid administrative leave since June 2016.

Lastly, during the course of the investigation, SJPD identified three suspects who conspired to bribe a uniformed member of the SJPD. The suspects are affiliated with the Duong Café, located at 2268 Senter Road in San Jose, and are associated to a criminal street gang in San Jose.
