A Melbourne woman who was sexually assaulted by a masked stranger while on an early morning walk has spoken out, saying she fears he will attack again.
The 30-year-old, known as Sarah, was walking down Sydney Road in Brunswick at about 6.20am on February 7 to meet a friend for their regular Sunday morning exercise when she noticed the man.
He was wearing a face mask and a hoodie and said nothing before or after sexually assaulting her.
Sarah says she yelled at him before he fled down a side street, and now she's worried he may strike again.
"It feels calculated and deliberate," Sarah told reporters on Thursday.
"To me, it's either already happened to someone else, or it will at some point. And I'm not OK with that."
Sarah and her friend have since abandoned their Sunday morning walks.
Detective Senior Constable Diane Jeffries said the Caucasian man, described as being in his late-20s or early-30s, followed Sarah for about one kilometre before attacking her.
Police believe it was a targeted attack, saying the man had attempted to conceal himself by wearing a face mask when it no was longer compulsory to do so.
"This type of behaviour is extremely concerning," Det Sen Const Jeffries said.
"It's a brazen attack in a busy street in Melbourne ... and it will not be tolerated.
"We're hoping to bring this person before the courts as soon as we can."
