About 4.30pm on May 1 the 18-year-old female boarded the fourth carriage of a train at Museum Railway Station bound for Campbelltown via the South Line.

Thirty minutes later a man sat next to her and allegedly indecently assaulted her.

She moved away from the man and alighted from the train at Auburn Railway Station, where she alerted station staff and police were contacted.

At the time of the incident, he was wearing a black t-shirt with white writing and a picture on the front; a red puffy jacket and blue denim jeans. He was believed to be carrying a backpack.
