A man has been charged with sexual assaulting an elderly woman at a train station in Melbourne's south-east.
The 87-year-old woman was on the platform at Aspendale about 11am on September 22 when a man asked her if she wanted money.
When she declined, the man kissed her on the cheek and allegedly sexually assaulted her, a police spokeswoman said.
The woman, who had a walking frame, managed to break free and boarded her train.
It's believed the man got on a Frankston-bound train, disembarking at Carrum Station.
A 40-year-old Frankston man was arrested on Tuesday morning and charged with sexual assault.
He was bailed to appear at the Melbourne Magistrates Court on December 15.
