Fresh charges have been laid against a junior doctor accused of planting a recording device inside a female staff bathroom at a major Melbourne hospital.

Ryan Cho, 27, was arrested at a home in Croydon today and interviewed by detectives.

He was charged with five further offences, including three counts of producing an intimate image, one count of using an optical surveillance device and one count of failing to comply with directions to assist.

He has been remanded to face the Melbourne Magistrates’ Court this afternoon.

Cho was initially charged with stalking and using an optical surveillance device on July 10.

Police allege the 27-year-old used a phone to record in a restricted staff bathroom at Austin Hospital in Heidelberg on July 3.

The device is believed to have been in place “for some time” before staff reported it, police said.

As part of the ongoing investigation, several additional hospitals where Cho worked between 2020 and 2025 have been identified as workplaces of interest.

These hospitals are located in Melbourne’s CBD and regional Victoria.

Police have begun contacting those workplaces, as well as staff potentially impacted during the time of Cho’s employment.

This process is due to take some time.
