THE DAILY SOURCE | MONROVIA, CALIFORNIA | OCTOBER 28, 2026
An officer sworn to uphold the law found himself on the other side of a police investigation after a civilian predator-hunting group accused him of arranging to meet someone he believed was an underage girl.
Leonardo Arturo Ruiz, an officer with the Los Angeles Police Department, was arrested on October 22 in Monrovia, California, following a confrontation captured on video by members of the civilian group YN_Vs_Preds.
The group alleged that Ruiz had been communicating online with someone he believed was a 16-year-old girl. In reality, according to the group's account, the supposed teenager was an adult posing as a minor as part of an online sting operation.
The allegations have not been proven, and Ruiz was subsequently released without criminal charges pending further investigation.
A Three-Day Conversation Ends in a Confrontation
According to the group's organizer, members exchanged messages with Ruiz for approximately three days before arranging an in-person encounter.
Instead of meeting the teenager he allegedly expected, Ruiz was confronted by members of the group, who accused him of attempting to meet a minor for sexual purposes.
Video circulated online shows a chaotic confrontation in which Ruiz reportedly attempted to flee before being physically detained by members of the group.
The encounter eventually drew a response from local police.
The circumstances were unusual: an officer whose profession involves enforcing the law was now the subject of allegations brought forward by civilians conducting their own investigation.
And unlike a routine police encounter, the confrontation was being recorded for an online audience.
Police Confirm Arrest, Investigation Remains Open
Monrovia police confirmed that officers responded to the 300 block of West Olive Avenue at approximately 9:59 p.m. on October 22.
Ruiz was arrested on suspicion of violating California Penal Code Section 288.4, which addresses arranging to meet a minor, or someone believed to be a minor, for lewd purposes.
According to police and jail records, Ruiz was released hours later without charges while investigators continued reviewing the case.
The release does not necessarily mean Ruiz has been cleared.
Retired LAPD Detective Moses Castillo told FOX 11 that investigators could examine both potential criminal conduct and violations of department policy.
In other words, the arrest made headlines, but the legal process is far from finished.
LAPD Places Officer on Administrative Leave
The Los Angeles Police Department confirmed it was aware of the arrest and was cooperating with the investigation.
ABC7 reported on October 28 that Ruiz had been placed on administrative leave. The department has not publicly disclosed the outcome of any internal disciplinary review.
The case also raises questions about civilian groups conducting undercover investigations and physically detaining suspected offenders.
Such operations can produce evidence and draw attention to serious allegations, but they can also create safety risks and complicate criminal investigations.
Ultimately, prosecutors must determine whether the available evidence supports criminal charges, regardless of how widely the confrontation circulates online.
What Happens Next?
As of October 28, Ruiz had not been criminally charged, and Monrovia police said their investigation remained ongoing.
Investigators may review the alleged online conversations, witness statements, and recorded confrontation before prosecutors decide whether to pursue the case.
The allegations against Ruiz remain unproven, and an arrest does not establish guilt.
For now, the video has attracted public attention, but the most consequential development has yet to occur: a formal charging decision.
