A Wellington man believes he stopped a woman being sexually assaulted by two men who've been accused online of numerous sex attacks in the city.
The police have launched an investigation and say they have received a small number of complaints but expect to get more.
There has been a flood of allegations on social media about a group of Wellington musicians who prey on women.
