Exclusive: A Melbourne University medical student has been caught filming young women at accommodation sites in the city.

Despite hundreds of secretly recorded photos and videos on his phone and laptop, the 23-year-old walked away with no conviction.

Bao Phuc Cao is supposed to be in Melbourne studying to become a neurosurgeon.He was living at RoomingKos, a CBD student accommodation in the city, when he preyed on young women.

A female student was showering when she noticed someone holding a mobile phone under her cubicle.

It belonged to Cao and he was arrested soon after.

Police then discovered hundreds of secret images and videos of young women.

There could be up to 150 alleged victims who were unknowingly filmed.

Cao pleaded guilty and he was sentenced to a Community Correction Order and forced to undergo a sex offender treatment program.

No conviction was recorded.

Sherele Moody from the Red Heart Campaign which documents the killing of Australian women and children said: “This is not a victimless crime, every one of those women have had their privacy invaded.

“It also means that if he does go on to become a doctor or a surgeon, his patients are not going to know what he’s been up to and what he could potentially get up to.”

A few months ago he was arrested again this time secretly filming a woman in the public toilets at District Docklands shopping centre.

He confessed, pleaded guilty and again no conviction was recorded.

“How many women have to be subjected to a perpetrator of this type of crime, and he literally gets away with it,” Moody said.

“How safe are the female students at that university right now?”

A Melbourne University spokesperson wouldn’t confirm if Cao is still a student due to privacy reasons but said the safety and wellbeing of staff and students was paramount.

“We are committed to eliminating and preventing sexual misconduct from our community and have robust systems and supports in place for our students and staff,” the spokesperson said.

“Any experience of assault, sexual assault and sexual harassment within our university community is unacceptable.”
