A man who challenged a group of Wellington musicians accused of sex attacks says he expects the number of complaints to rise even further.
Wellington detectives are now investigating at least 20 separate reports of sexual assault, violence and drugging. Allegations made online say the musicians targeted women, men and minors.
One man challenged one of the group after a friend of his was threatened.
He told RNZ reporter Hamish Cardwell that since the allegations were first circulated on-line a number of survivors have told him awful stories about their experiences.
The Police say anyone with information should contact them.
