The organisation representing Alice Springs native title holders say the dynamic of street violence and law-breaking in Alice Springs is changing.
Darryl Pearce from Lhere Artepe says some of the problems are being caused by Aboriginal people from remote communities while they are in Alice Springs.
He says the Northern Territory Government is responding with extra police patrols, but the existing models are not changing people's behaviour.
"We're seeing people starting to engage in a process of basically saying 'up yours' and doing things which are starting to ramp up the engagement with police," Mr Pearce said.
"So in reality what we're seeing is a whole changed dynamic in terms of the relationship between people and it's something which is of major concern to us."
