Search leads to gang

The search for a missing Dunedin woman has led to the Mongrel Mob headquarters in Christchurch, but police say it is too early to speculate on a possible breakthrough in the disappearance of former prostitute Tui Tania Marama McIntosh.

It is understood luminol testing - used to detect invisible traces of blood - was done when forensic samples were taken at the gang property during a major drugs bust last week.
