A serial masturbator seems to be terrorising woman at a popular beach in the southern suburbs of Perth.
A woman first warned of the threat on Sunday, claiming she was running on a coastal path just past South Beach in North Coogee around midday when she spied a man committing a lewd act.
She has since reported the incident to police.
"It was very disturbing," the woman wrote on social media.
"I ran pass him once and at that time he still had a towel around him but he took it off when he saw me and as I didn't have my phone on me I panicked and ran towards the car park and walked back with a group of people.
"After we've passed the cattle race I thought maybe he's gone and I started running by myself again and he was masturbating at the next turn... I ran back to the group of people and borrowed their phone to call the police but he was gone by then."
It appears the area around the coast in North Coogee is a popular spot for "flashers" and those committing indecent acts.
Another woman posted on social media saying she spied a man committing a lewd act in the dunes of the beach on Saturday.
"A flasher seen performing a lewd act on himself on the dunes at CY O'Connor dog beach this afternoon," she wrote.
" It appeared that he wanted to be seen as was in full view of people on the beach. A fellow dog walker also spotted him and called the police. He was seen at the south end of the dog beach."
Another Facebook-user responding to the original post claimed she spied a man behaving indecently at the same beach a few years ago.
"A man jumped in front of my car naked and started masturbating," she wrote.
"He's lucky I didn't run him over. I reported it to police at the time. It seems like the area is favoured by a few unsavoury people. Be aware and take care."
Police have been contacted for comment.
