Police are investigating a possible serial flasher in Canterbury.
Nik Croxson told the Herald she was on a walk near Spencer Park when she was approached by a woman in a car.
"She stopped next to me to warn me she had seen a naked man and that I might want to walk a different track. She was calling the police while we spoke."
"She said she had been walking a forest track near the beach when she saw a man who was naked and masturbating up near the sand dunes," Croxson said.
