There are fears the person responsible for a spate of sexual assaults in Wellington may never be caught.
There are potential links between as many as 12 sexual assaults in the city, and questions are being asked over police's handling of some of them.
In 2011, while walking home from Massey University, Grace Leung was randomly attacked.
"A man grabbed me from behind and picked me up and dragged me down the side of an empty building," she told Newshub.
She managed to fight him off, and police are investigating whether that attack may have been the trigger for a number of others that followed.
"It does seem like the behaviour of the attacker was quite similar in some of these cases."
There are doubts over how seriously some information was taken by police. In 2014, Ms Leung thought she recognised a sketch of her attacker.
She rang the police, but she says that call was effectively ignored.
"There was no follow up to my call, and in reviewing my case notes, they were not reviewed."
Two other reported attacks happened in an alleyway near Victoria University in 2014. It's nicknamed 'rape alley', and people actively avoid it.
CCTV cameras have since been installed and there are lights at either end, but it's still deemed unsafe.
Police wouldn't front for interviews on Sunday, saying they are continuing to investigate a number of assaults over several years and are working to establish whether there is a connection between them.
It's little comfort for victims like Ms Leung, who live each day knowing their attacker still hasn't been - and may never be - caught.
