Teen good Samaritan molested by NSW driver

A teenage woman was allegedly molested in Sydney by a man who persuaded her to get into his car before offering her a breast check.

Police say the 19-year-old was approached on the street at Ashfield on June 27 by a man who asked for directions then insisted she get in to his ute to show him the way.

The man allegedly indecently assaulted the teen as they drove towards the city centre, claiming he had medical training and knew a way to detect breast cancer.

A 47-year-old man was arrested at Hurstville in Sydney's south on Monday and charged with three counts of indecent assault.

He was granted conditional bail and is due to face Sutherland Local Court on August 11.
