Cha Eun Woo has been pulled into a privacy investigation in Seoul after a woman in her 50s allegedly placed hidden listening devices beneath a café table where the actor and singer was having a private conversation. The incident is being investigated by police in Yongsan, with officers examining how the devices were planted and whether they actually captured any conversation involving the ASTRO star.
According to a report from Korean outlet Sports Chosun, the woman allegedly visited the same café on two occasions in August while Cha Eun Woo was there. Police reportedly believe she placed the devices beneath the table during those visits and later returned to the café, where investigators caught her.
The case has now moved beyond the initial discovery of the devices, with police examining the woman’s phone and the equipment itself. Investigators are also trying to establish whether she acted alone, how she obtained the devices and what she intended to do with any material that may have been recorded.
What happened at the Seoul café?
The alleged incidents took place at a café in Seoul’s Yongsan District, according to the reports. Police believe the first incident happened on August 23, when Cha Eun Woo was at the café having a private conversation with an acquaintance.
The woman allegedly returned to the same location on August 29, when Cha Eun Woo was again present. Investigators believe additional listening devices were placed beneath the table during the second visit, bringing the reported number of devices involved across the two occasions to five.
The discovery became more significant when the woman allegedly returned to the café again to retrieve the equipment. Police reportedly intervened at that point and took action against her, turning what might have remained an undiscovered privacy breach into a formal investigation.
The key question now is whether the devices were capable of recording conversations and, more importantly, whether anything involving Cha Eun Woo was actually captured. Police are examining the equipment as part of their investigation rather than assuming that a recording was successfully made.
Police examine devices and woman’s phone
The woman has reportedly been booked by Yongsan Police Station for an alleged violation of South Korea’s Communications Secrets Protection Act. She was initially emergency-arrested at the café, but reports say prosecutors did not approve the emergency arrest, after which she was released and is now being investigated without detention.
Police have also secured her mobile phone for forensic examination. That step could help investigators determine whether she was communicating with anyone about the alleged surveillance, how the devices were obtained or whether there was any plan for using material that might have been recorded.
Authorities are also looking into the woman’s possible motive. At this stage, the reports do not establish why Cha Eun Woo was allegedly targeted or whether the woman intended to distribute, sell or otherwise use any private conversation.
That distinction matters because the investigation is still developing. The reported placement of recording devices does not by itself establish that a private conversation was successfully recorded, and police are still working to determine exactly what happened.
Cha Eun Woo’s career continues during military service
The investigation comes while Cha Eun Woo remains one of South Korea’s best-known singer-actors. He first gained widespread attention as a member of ASTRO before building a successful acting career through dramas including True Beauty, Wonderful World and A Good Day to Be a Dog.
His latest major screen project is Netflix’s The WONDERfools, where he stars opposite Park Eun-bin. Netflix describes the series as a 2026 limited series set around the turn of the millennium, with Cha Eun Woo playing Lee Un-jeong, a civic servant who becomes involved with a group of unlikely characters who develop superpowers.
The series premiered globally on Netflix on May 15, 2026, and has eight episodes. Netflix’s official material also confirms Cha Eun Woo’s role alongside Park Eun-bin, Choi Dae-hoon and the rest of the ensemble cast.
For now, however, the café investigation remains separate from his entertainment activities. Police have not publicly established that any private conversation was successfully recorded, and further forensic examination of the devices and phone could provide more information about the circumstances.
What happens next in the investigation?
The next stage will likely focus on evidence rather than speculation. Investigators need to establish when the devices were placed, whether they were operational, what they were capable of recording and whether any files or recordings were recovered from them.
The woman’s phone could also become an important part of the case if investigators find messages, searches or other information connected to the alleged surveillance. Police are additionally examining the circumstances surrounding her visits to the café and the reason she allegedly returned to collect the devices.
For Cha Eun Woo, the most important unresolved issue is whether his private conversation was actually captured. Until investigators complete their examination, reports about the incident should be treated as allegations rather than confirmation that a recording exists.
The case also highlights the difficult privacy line surrounding celebrities, who can attract intense public attention even during ordinary private moments. In this instance, the investigation will determine whether the reported conduct amounted to a violation of South Korean law and what evidence can ultimately be established.
