Between 9am and 10am, police from Oamaru and Timaru - with armed offenders squad members from Dunedin - executed two search warrants in Hull and Clyde Sts, Oamaru, following an aggravated robbery in Timaru on Monday, Detective Sergeant Hannah Booth, of Oamaru, said.
She said the search warrant was in relation to "one person who is currently residing at that [Hull St] address".
"And they are known to police."
Shortly after 9am, about a dozen armed police swarmed the Hull St house.
