The young girls were on Kimberley Place, Miranda, when a 23-year-old man allegedly approached them and initiated a conversation.

The girls ran away, but a short time later they saw the man again near Forest Road, and ran away from him again.

One of the girls fled to a nearby house and knocked on the door for help, police said. The 23-year-old man allegedly followed her to the door where he was approached by the occupant of the house who called police.

A short time later police found the man on the Kingsway, Gymea. He was arrested and taken to Miranda Police Station and charged with stalking and intimidating with intent to cause fear of physical harm, as well as offensive behaviour.

He was refused bail and will appear in court on Friday.

Police have reminded parents to discuss the 'Safe People, Safe Places' messages with their children.
