The activity on Walnut Tree began this afternoon and is believed to be related to an alleged gang fight.

It is understood weapons were involved but it is not known if anybody has been injured.

The search now seems to be diminishing, though police have not yet announced any arrests.

The police helicopter is still hovering overhead.
