Transit Crime Investigation Unit detectives have released additional CCTV footage as their investigation into a sexual assault on a city-bound train last year continues.
Investigators have been told a woman boarded the train at Thornbury Railway Station about 9.35am on 16 May 2018.
She was followed onto the carriage by a man, who repeatedly harassed and sexually assaulted her.
The 51-year-old woman moved away a number of times before exiting the train at Flagstaff Railway Station, where the man continued to follow her and try to engage her in conversation.
She alerted staff at the station and the man fled the scene.
Transit police are appealing for information as part of Operation Report It, which encourages people to call out crimes on public transport when they see it.
Inspector Andrew Gustke said the man’s relentless behaviour was hugely concerning and may not have been an isolated incident.
“No one should feel unsafe or uncomfortable when taking public transport,” Insp Gustke said.
“The victim made it clear she was not interested – the fact he has continued this behaviour after his advances were rejected suggests there was no remorse.
“We need people to say something if they see something.”
Detectives are today renewing their appeal for information, with police and PSOs to engage with commuters at Southern Cross Railway Station this afternoon.
Investigators have also released new images and CCTV in the hope someone can help identify the man.
He is perceived as Pacific Islander or Asian in appearance and aged in his 20s or 30s.
At the time of the incident he was wearing a New York Yankees cap, denim jacket with a black and white hoodie underneath, tan-coloured pants and dark shoes.
Investigators also wish to speak to an anonymous caller who contacted Crime Stoppers on 13 March this year and may hold vital information.
“There are thousands of commuters catching trains and trams at that time of the day and someone out there will recognise this man or recall the incident,” Insp Gustke said.
“If you’re on a train or a tram and witness someone engaging in criminal or antisocial behaviour, we want to hear from you – your information could be the key to making sure that person doesn’t offend again.”
Commuters are reminded they can report crimes to PSOs as well as local police, or to Crime Stoppers on 1800 333 000 or online at www.crimestoppersvic.com.au
