A man has been taken away by Waikato Armed Offenders Squad members after a search warrant was instigated at a Hamilton house.
Heaphy Tce, in the suburb of Fairfield, was blocked off by police as armed officers stormed the property from 6.30am today.
Local residents reported hearing noises but didn't think much of it.
One said she first thought the noises were being made by animals, before her husband went and had a look.
To their shock they found several AOS staff lined up outside the house, near the intersection with Clarkin Rd, pointing their rifles at the house.
