Three girls were left in a state of shock when a man riding a Honda Scoopy-i shouted obscenities at them, whilst fondling himself with his genitals in full view of the teenage girls.
The year ten students were travelling on a motorbike and made attempts to evade the culprit but the depraved man managed to follow them for over five kilometres.
The girls managed to capture their harasser on their mobile phone, presenting the image to police as evidence.
The man was wearing a blue shirt, black shorts and had long hair.
If you think you know the pervert, please get in touch with local police before he strikes again.
