Police, including armed offenders squad members, swarmed on an Oamaru address this morning as part of a methamphetamine raid.
Detective Sergeant Hannah Booth, of Oamaru, said police, including armed offenders squad members, carried out the search warrant at the Parsons Rd property.
The raid was related to the supply of methamphetamine and connected to the Mongrel Mob, Booth said.
"It is believed to be a Mongrel Mob pad,'' she said. "So, as local police we are really concerned about that.''
She could not comment on this stage on what had been found at the property, a former milk treatment station near the edge of the town.
