A 13-year-old school girl told Cabramatta police she was approached by a man on her way to school last week.
The girl was walking on Lansdowne Road in Canley Vale on Friday, November 23 after 8.30am when a white Toyota Hiace van pulled up beside her.
She told police the man spoke to her but she ignored him and kept walking.
The man did not get out of the van or touch the child.
Police are appealing for anyone who may have seen the van in Lansdowne Road on Friday morning.
The man is described to in his mid 40s, possibly of Indian or sub-continental appearance, dark complexion, wavy black hair and dark brown eyes.
He was wearing a long-sleeved black hoodie with an orange work safety vest.
Anyone with information should contact Crime Stoppers on 1800 333 000.
