Singaporean trainee doctor in Australia faces fresh charges for secretly filming hospital colleagues

A Singaporean doctor working in Australia, who is under investigation for stalking and using an optical surveillance device to film women, has been hit with additional charges. Victoria Police confirmed that 27-year-old Ryan Cho now faces five further offences. These include three counts of producing intimate images, one count of using an optical surveillance device, and one count of failing to comply with a direction to assist authorities. Cho was arrested at a property in Croydon on 25 July 2025. He had previously been released on bail after his initial arrest for allegedly hiding a mobile phone in a restricted staff toilet at the Austin Hospital, where he was employed as a trainee surgeon.

Ongoing Investigations Across Multiple Hospitals

Police have identified other hospitals where Cho worked between 2020 and 2025 as “workplaces of interest” in the ongoing investigation. These facilities include hospitals in Melbourne’s CBD and regional Victoria. Authorities have begun contacting these hospitals and individuals who may have been impacted during Cho’s employment. According to court documents cited by ABC News, Cho was found in possession of approximately 4,500 intimate videos involving at least 460 alleged victims. The footage was linked to the Austin Hospital, the Royal Melbourne Hospital, and the Peter MacCallum Cancer Centre.

Nurse Discovered Hidden Phone in Toilet

Court documents allege that Cho was observed “loitering” around the emergency department on multiple occasions, either well before his shift began or when he was not rostered to work. The documents also stated that, in early July, a nurse at the Austin Hospital discovered a mesh bag containing a mobile phone in a staff toilet. Believing it to be recording, the nurse reported the incident to management. A few days later, hospital security found the same bag again, prompting police involvement. Cho was subsequently arrested, and authorities seized two mobile phones, a laptop, a hard drive, several white mesh bags, and removable hooks from his home. “The mesh bags and removable hooks seized … are of the likeness of the ones used in the commission of his offending at the Austin Hospital,” police alleged in court documents. He allegedly refused to provide authorities with passwords to the devices.

Footage Seized

Investigators revealed that one of the laptop hard drives contained 10,374 videos and images. Another seized phone reportedly contained three hours of footage, including recordings of Cho setting up the device and more than an hour of footage showing the intimate regions of three women. Police alleged in court documents that most of the victims appear to be female doctors, nurses, paramedics, and other staff from medical facilities where Cho had worked since 2021. Cho allegedly categorised the videos according to hospitals, wards, and the names of the alleged victims. “Investigators have received reports from staff and management that they are suffering trauma … and are fearful of using the hospital facilities,” police stated in court documents. “Staff are no longer feeling safe in their workplace,” the documents added.

Bail Denied

Cho has contested the charges, ABC News reported. According to the Australian Health Practitioner Regulation Agency, his medical licence has been suspended, and he is prohibited from practising in Australia. The court denied him bail on the grounds that he had no ties to Victoria and was considered a flight risk. He is scheduled to return to court in November.
