"The female resisted the assault by kicking and punching the male and finally scratching his face. In a gutsy display of courage the victim was able to repel what was clearly a premeditated and sinister attack," Litherland said.
The man, described as a skinny Pacific Islander or Indian aged in his late 20s or early 30s, with short black hair and a skinny build, would now have scratch marks visible on his face.
"He ran back in the direction of the train station and the victim, who was left bruised and
shaken, sought assistance from the police."
The man was wearing a long-sleeved grey sweat shirt, black full length pants and black shoes.
Police would like to hear from anyone who saw the man on the train or who knows who he is.
"The male will have difficulty concealing the injuries to his face."
