Investigators have been told a male inappropriately exposed himself to a pair of ten-year-old girls along the Ferny Creek Bicycle Trail near the Knox Regional Netball complex at approximately 4:15pm on Wednesday 12 August 2020.
The male is alleged to have appeared from behind a shelter wearing nothing but purple underpants while staring at the two girls.
Police have released a digital face image of the man in hope that he may be known to someone or they may have seen the incident take place.
He is perceived as being between 30 to 40 years old, average build, brown hair in a ponytail, a short beard and brown eyes. At the time of the incident, he was wearing all dark clothing with purple underpants briefs.
The man police wish to speak to was seen riding a black bike and had a black and white bicycle helmet with him.
