Fake undercover police car leads to arrest after Tokyo crash; passenger injured
Tokyo police arrest 23-year-old after a December 21, 2025 crash while driving a fake undercover police car; passenger injured and vehicle illegally modified.
The Metropolitan Police Department arrested a 23-year-old man from Toda, Saitama Prefecture, on Tuesday, May 19, 2026, on suspicion of dangerous driving resulting in injury and operating an illegally modified vehicle. Police say the arrest followed an investigation into a December 21, 2025, collision in Nerima Ward in which the driver, while under the influence of alcohol, struck a utility pole in a car altered to resemble an undercover police vehicle. The incident has renewed scrutiny of unauthorized use of police-style equipment on private cars and raised safety concerns among local residents.
Arrest and charges
The Metropolitan Police Department charged the man with dangerous driving that caused injury and for modifications to his vehicle that are not permitted under traffic laws. Authorities said the suspect admitted to the allegations during questioning and acknowledged that he had been drinking before driving. Investigators added that the case remains under active review as they consider further procedural steps and possible additional charges related to public deception.
Details of the December 21, 2025 collision
According to police reports, the crash occurred around 1:20 a.m. on December 21, 2025, on a local road in Nerima Ward when the driver lost control and hit a utility pole. The vehicle sustained significant front-end damage, and emergency responders transported one passenger to hospital where she was treated for multiple injuries. The car was impounded and taken to Nerima Police Station for inspection as part of the investigation.
Injuries to passenger and medical condition
The passenger, a 22-year-old woman employed as an office worker, suffered a broken rib among other injuries and was described by police as seriously hurt following the collision. Hospital staff provided treatment and the patient’s condition has since been reported to be stable, according to police statements. Investigators say they will continue to monitor the victim’s recovery as the case proceeds and will coordinate with prosecutors on the charges.
Patterns of dangerous driving recorded by police
Officers investigating the vehicle found evidence the driver repeatedly violated traffic rules before the crash, police said. The man allegedly ran red lights and exceeded speed limits on more than ten occasions while activating a siren, flashing red lights and broadcasting warnings to nearby drivers. Neighbors and witnesses had reported multiple episodes of unusual driving behavior prior to the December collision, prompting detectives to widen their inquiry into the vehicle’s movements.
Vehicle modifications and impersonation concerns
Police examinations showed the car had been altered to mimic an undercover police vehicle, including installation of red lights, a siren system and an electronic device for broadcasting messages such as warnings to other drivers. Investigators are probing who carried out the modifications and whether any laws beyond vehicle equipment regulations were violated by impersonating law enforcement. The Metropolitan Police Department emphasized that unauthorized use of police-style lighting and signaling devices is prohibited and poses risks to public safety.
Suspect’s statements and motives
When questioned, the suspect said he had asked a friend to change the vehicle’s appearance because he wanted a car that stood out from others, and he acknowledged enjoying the attention he received when people treated the vehicle as a potential police car. Investigators noted the suspect admitted to operating the car while intoxicated and to engaging the siren and lights on multiple occasions. Police are examining the suspect’s interactions with the person who modified the car and whether any third parties may face legal consequences for assisting with the alterations.
Ongoing investigation and legal next steps
The Metropolitan Police Department is compiling evidence, including witness testimonies, traffic camera footage and a technical inspection of the vehicle, to present to prosecutors. Authorities say they will determine whether to pursue further charges related to impersonation of law enforcement or public nuisance offenses in addition to the existing counts. The Nerima Police Station remains the point of contact for inquiries about the case as detectives complete their report.
Public reaction to the case has been one of alarm, with community groups calling for stricter enforcement of equipment laws and better monitoring of dangerous driving. Police urged members of the public who witnessed the vehicle’s behavior or who have additional information about its modifications to come forward to assist the inquiry.
The investigation continues as prosecutors review the evidence and the injured passenger recovers from her injuries.
