David Richard Parker (45) appeared in the Dunedin District Court this week, where he was sentenced to 10 months’ jail.
At recent hearings he strongly protested against his treatment, mentioning the "High Court", "Privy Council" and "treason".
Despite his erratic behaviour, a psychological report deemed him fit to engage with the legal process.
On December 8 — two days after being released from the Otago Corrections Facility — Parker visited Work and Income’s Dunedin office in Princes St.
After speaking to staff, the defendant swiftly angered.
As he was removed from the building by security, he called everyone "Nazis".
"I’m going to shoot you guys," he said.
The premises subsequently went into lockdown, but police did not find Parker until he committed another similar outburst.
The next day he entered the Dunedin City Council building and made more inflammatory comments before returning to the scene of the original crime.
The court heard Parker was refused entry to the Ministry of Social Development building by security and was eventually found by police on the grass in The Octagon.
A chase ensued and the defendant was eventually collared while trying to hide in a church grounds.
Parker resisted being loaded into the patrol car and he continued to act out back at the station.
After being placed in a cell he remained "loud, aggressive and abusive", court documents said.
He removed his pants, flashed his rear at officers before turning and "waving" his appendage at them.
The defendant then defecated on the floor and used it to write "Nazi" on the window.
Later, Parker managed to grab hold of a constable through an open flap of the cell door and took a baton from an officer who came to help.
It took eight officers to subdue him.
Parker was convicted of threatening to kill, wilful damage, assault and doing an indecent act.
