Members of the Armed Offenders Squads swarmed a property in central Dunedin’s Heriot Row this afternoon.
A police spokesman said they were called to an incident about 4.50pm, but would not elaborate on the nature of the callout other than that police were armed as a precaution.
A man was seen being led away by police at about 6.30pm.
Earlier, armed police officers established a cordon at the intersection with London St, closing Heriot Row to traffic.
