Los Angeles police on Friday announced the arrests of four people suspected in “knock-knock”-style burglaries, and detectives are trying to determine if the suspects are part of a burglary crew combing Southern California for unwitting victims.

Officials suspect that the four have committed “knock-knock”-style burglaries in areas as far apart as the San Fernando Valley, the San Gabriel Valley and the South Bay.

Around 10:30 a.m. Monday, investigators from the Los Angeles County Sheriff’s Department Major Crimes Bureau, Burglary-Task Force followed a car with suspected gang members believed to be involved in organized residential burglaries, authorities said.

The car was followed into residential neighborhoods in Northridge and Porter Ranch before going to San Fernando and Sylmar, sheriff’s department officials said.

Authorities said documented L.A.-area gang member Malik Trevon Oaks, 18, of Los Angeles, exited the car and walked into a cul-de-sac on the 14600 block of Rex Street in Sylmar.

Detectives allege the suspects — including Oaks — broke into a home by smashing a side window and ransacked the residence.

After detectives coordinated with Los Angeles Police Department officers, the LAPD attempted to conduct a traffic stop, which resulted in a brief pursuit, officials said.

Authorities said the suspects exited the 5 Freeway near Paxton Street before stopping and running on foot into the neighborhood. But within minutes, a sheriff’s detective detained and arrested Oaks, who was hiding in an underground walkway for pedestrians, authorities said.

A short time later, LAPD officers with a K9 team found documented L.A.-area gang member Rondell Marques Fields, 32, of Los Angeles hiding in a nearby backyard.

A third suspect was not found, but property taken from the home and additional evidence was found inside the car.

The men were arrested on suspicion of residential burglary as well as criminal street terrorism. Fields was also arrested in connection with felony evading a police officer. They were arraigned on Wednesday, but it was not immediately clear how they pleaded.

Officials said the investigation is ongoing, and both agencies are trying to determine if this is a burglary crew responsible for additional crimes in the Los Angeles County and San Fernando Valley areas.

The next day, at 11 a.m., detectives from the task force conducted an investigation into what they believed was a suspicious gray Porsche Cayenne SUV used in residential burglaries in the Mid City area of Los Angeles and in the San Gabriel Valley.

Investigators followed the SUV into Gardena, where it drove to the 14500 block of Wadkins Avenue.

Detectives watched as a passenger, later determined to be documented Los Angeles-area gang member Ricky Holmes, 39, of Los Angeles, “disappeared” around a side yard.

Minutes later, authorities said, Holmes left the residence from the front door carrying a bag before entering the SUV, which drove away. Detectives later confirmed a side window to the home was opened, and the interior of the residence was ransacked.

Within minutes, the SUV was stopped and two suspects — including Holmes — were apprehended with stolen property and cash taken from the home recovered, authorities said.

Holmes was arrested on suspicion of residential burglary, conspiracy to commit burglary, criminal street terrorism and resisting arrest.

A second suspect, Jasma Garrison, 34, of Los Angeles, was also arrested on suspicion of the burglary, conspiracy and street terrorism crimes but additionally arrested for felony evading police. Garrison, authorities said, is a suspected street gang associate and a four-time convicted felon.

Holmes was arraigned on May 18 in Torrance and remains in custody, but it was unclear how he pleaded. Garrison, who is not in custody, has a court appearance set for June in Torrance.

Investigators are trying to determine if the suspects are responsible for additional “knock-knock”-style crimes in Los Angeles County, including the South Bay.
