A trainee surgeon has renewed his push for bail despite facing scores of fresh charges over allegedly secretly recording staff in toilets at three hospitals.
Police have laid another 127 charges against Ryan Cho, a Singapore citizen who has been been living in Australia as a permanent resident after completing a Monash University medical degree.
The 28-year-old was first arrested on July 10 after a phone concealed in a mesh bag was discovered in a staff toilet at the Austin Hospital in Melbourne's northeast.
Cho was initially charged with offences including stalking but was released on bail, with police seizing his two mobile phones, a laptop, several white mesh bags and removable hooks.
He was arrested for a second time in late July after police analysed the devices and allegedly uncovered more than 10,000 videos and images.
The material, created between 2021 and 2025, shows staff using the toilet or shower facilities, police allege.
All six initial charges against the junior doctor were connected to the Austin.
The extra charges relate to the Austin, Royal Melbourne Hospital and Peter MacCallum Cancer Centre, where it is alleged a phone was used to record in staff toilets.
"The investigation is continuing with further medical facilities where the man worked between 2020 and 2025 still of interest," police said.
"Police expect to identify further alleged victims however working through this process is expected to take some time."
Cho, who was suspended from working as a junior surgeon, was refused bail on July 25 after a magistrate found the risk to the community could not be reduced through stringent conditions.
He is expected to make another bid for bail at a hearing in the Supreme Court on Friday.
