Stranger 'assaults teen' on Sydney train

A man who allegedly indecently assaulted a 16-year-old girl on board a train in Sydney's south has been arrested.

It's alleged the man sat down next to the teenager and assaulted her after she boarded a train at Kogarah Railway station on Monday afternoon.

He was on Thursday charged with two offences, including interfering with the safety of others, and granted conditional bail to appear at Sutherland Local Court next month.
