Houston police seek more victims after Phillip Cerf arrest

Houston police are asking anyone who may have been harmed by Phillip Cerf to contact investigators after his recent arrest in a case tied to multiple alleged sexual assaults. The public appeal adds urgency to an investigation that authorities say may involve more victims in the Houston area.

The Houston Police Department said detectives believe other people may have relevant information or may have had encounters with Cerf that have not yet been reported. Police made the request after announcing his arrest, and the department is now trying to determine the full scope of the allegations.

Houston police expand the search for possible victims

According to the department, detectives are working to identify additional complainants after Cerf was arrested following allegations of multiple rapes. Police have not asked the public to speculate about the case. They are asking people with direct knowledge to come forward so investigators can compare accounts and build a clearer timeline.

Cases involving repeated sexual assault allegations often rely on victim statements, corroborating evidence, and patterns that may connect separate reports. A public request for more victims or witnesses can help investigators find incidents that were never formally documented. That step can also help prosecutors assess whether additional charges are warranted.

Why the public request matters now

When police issue a call like this, timing matters. Some victims may not realize their experience matches a larger investigation until an arrest becomes public. Others may have hesitated to report earlier and decide to speak after learning that other allegations have surfaced.

Houston police have not publicly detailed every allegation connected to Cerf in the reporting cited here. What is clear is that investigators believe more information may still be out there. Anyone with information that could assist the case is being urged to contact HPD.

The case remains under investigation, and any new reports could shape the next steps taken by detectives and prosecutors. ABC13 reported on the arrest and the department's effort to locate additional victims, with police asking anyone affected to come forward through official channels.
