Woman in Kansai questioned for about an hour by fake police on phone and Zoom; analysis for Osaka police found the detective's face possibly an AI deepfake

In June 2026 a woman in her thirties in Japan's Kansai region received a call from a man claiming to be an Aichi Prefectural Police officer, who said a cash card in her name was linked to a fraud ring and that she was a suspect. She was moved to a Zoom call where a second man, presented as a detective, showed a police notebook, questioned her and told her to search her home on camera for her My Number card. Suspecting fraud, she recorded the exchange and ended it after about an hour; she told reporters the pressure left her flustered and feeling like a culprit. The Osaka Prefectural Police published part of the recording in August, and an analysis it requested from Trend Micro found the detective's face was possibly a deepfake altered with AI (Yomiuri, Asahi, FNN, NHK). No loss is reported.

AI system as recorded: Unidentified face-altering tool; an analysis by Trend Micro for the Osaka Prefectural Police found the detective's face on the video call was possibly an AI deepfake

What Happened

The call. The woman told Yomiuri, Asahi and FNN that in June 2026 (late June, per Asahi) a man introducing himself as an officer of the Aichi police's community safety division called her mobile phone, told her a cash card in her name had been found with an arrested fraud ring and said she was under suspicion. She was passed to a second man, who said he was from the investigation division, and about 45 minutes after she answered was moved to a Zoom call (Asahi). On screen a man in a suit and glasses gave his unit and name and showed a police notebook before his camera went off after about 30 seconds (Asahi). She was told not to tell anyone, asked to show her My Number card and told to search her home for it while on the video call (Asahi). She had recognised the pattern from the news, began recording and decided to pretend to be taken in (Asahi), and ended the exchange after about an hour; Yomiuri gives the video call as lasting an hour and FNN the exchange as over an hour.

Her experience. She told Yomiuri that the caller spoke in a cornering way and that partway through she began to feel as though she were the culprit; she told Asahi the caller was overbearing, that she became quite flustered and that she nearly got drawn in even though she knew it might be fraud; she told FNN the talk left no room to object.

The analysis. The Osaka Prefectural Police published part of the recording on 12 August 2026 as a warning video. The police asked Trend Micro to analyse it, and the result was that the self-described detective's face was possibly a deepfake altered with AI; the police believe the technology was misused so that a fraud-ring member's face would not be known (Yomiuri). NHK and FNN report the same finding as a possibility. No tool is identified and no arrest or loss is reported.

Reported harm

The woman says the hour-long interrogation left her flustered, feeling as if she were a culprit and close to being drawn in, and she was pressed to search her home on camera and give personal information (Yomiuri, Asahi, FNN). No loss is reported.

How Harm Occurred

A fake detective, whose face an analysis for the Osaka police found was possibly altered by AI, questioned the woman on a video call, accused her of involvement in fraud and pressed her to search her home and disclose personal information; she reports feeling cornered and drawn in, and ended the call before any loss.

Outcome

Pending

The woman gave her recording to the Osaka Prefectural Police, which published part of it on 12 August 2026 as a warning video and had it analysed by Trend Micro (Yomiuri, FNN). No arrest or loss is reported in the inspected sources.

What remains unknown

  • Who made the call and from where; no arrest is reported.
  • Which tool, if any, altered the face; the analysis states a possibility and its full reasoning (in the paywalled part of the Asahi article) was not read.
  • Whether the woman's voice-call partner, the self-described Aichi officer, was also altered.

What the evidence supports

AI involvement: suspected. The woman was questioned over Zoom by a man presented as a detective who showed a police notebook and pressed her to search her home and disclose personal information. An analysis of her recording by Trend Micro, requested by the Osaka Prefectural Police, found that this man's face was possibly a deepfake altered with AI (Yomiuri), and the police believe the technology was used to hide the caller's face. Asahi reports that this man was on camera for about 30 seconds, giving a unit and name and showing the notebook, before his camera went off, and that the demand for her My Number card and the instruction to search her home followed on the same call. The face-altered persona presented the detective who questioned her. The analysis states a possibility, the tool is not identified and the paywalled part of the Asahi article was not read, so the status is suspected.

4 claims: 4 reported. What the statuses mean

Reported In June 2026 a woman in her thirties living in the Kansai region received a call from a man who said he was an officer of the Aichi Prefectural Police, told her a cash card in her name was linked to a fraud ring and that she was under suspicion, and had another self-described detective question her over a Zoom video call while showing a police notebook; the exchange lasted about an hour before she ended it.

Causal attribution. The account is the woman's, given in separate interviews to Yomiuri, Asahi and FNN (one witness), and shown in the recording she made and gave to the Osaka police.

Reported An analysis of the recording by the security company Trend Micro, requested by the Osaka Prefectural Police, found that the face of the self-described detective on the video call was possibly a deepfake altered with AI; the police believe the technology was misused to hide a fraud-ring member's face.

Causal attribution. One origin: the Trend Micro analysis commissioned by the Osaka police, as relayed by the police and the outlets. It states a possibility, so AI involvement is suspected.

Rajasthan: a social-media influencer's video of a Ganga dip at Haridwar was manipulated with AI into an objectionable reel that went viral; she says she is mentally disturbed and cannot leave her house, and filed a cyber-crime complaint on 16 September 2026

A Rajasthan social-media influencer visited Haridwar with her family in June 2026 and on 6 June uploaded to Instagram a short video, recorded by relatives, of herself taking a dip in the Ganga at Har Ki Pauri wearing a salwar suit. About two months later she found that the video had been manipulated with AI into an objectionable version showing the same movements with her face and body portrayed 'in a shameful manner'; the fake reel went viral in the week before 20 September and drew objectionable comments and re-sharing. In a public appeal she asked whoever uploaded it to remove it, saying it was a matter of her dignity, that she was mentally very disturbed and had reached a point where she could not step out of her house. She filed a complaint with the cyber-crime police on 16 September 2026; the investigating Rajasthan Police Service officer said they were trying to identify who created and circulated the video and to have it removed, and that identifying the accused would take time. Dainik Bhaskar's English edition reported the case on 20 September in a 'Sunday Big Story' that does not name her.

On 25 October 2025 the Telugu actor and former Union minister Konidela Chiranjeevi gave Hyderabad cybercrime police a written complaint that several pornographic websites were publishing obscene videos made with AI that morphed his face and likeness, and asked for a criminal and technical investigation and removal of the content, including from mirror sites. Police registered a case under Sections 67 and 67A of the IT Act, several sections of the Bharatiya Nyaya Sanhita and the Indecent Representation of Women (Prohibition) Act. In the complaint he said the videos caused severe and irreparable harm to his reputation and personal and emotional distress to him and his family. He had already obtained an ad-interim injunction from the Hyderabad City Civil Court protecting his name, image and likeness (Gulf News); V6 Velugu reports that he had gone to that court in September 2025 over the same kind of deepfake videos and that on 26 September it ordered their removal. A September 2026 NewsX recap reports that Hyderabad Police Commissioner V C Sajjanar said the cybercrime team was working to trace those responsible.
