Christchurch Man’s DIY Arrest Leads to Dual Convictions

A Christchurch man took the law into his own hands after becoming frustrated with police inaction regarding his assault case. Following an incident in December 2024, where he was attacked by David Hoffman, Steven Gardiner attempted to execute a citizen’s arrest on Hoffman, leading to a chaotic confrontation that resulted in multiple convictions.

Gardiner, 38, gathered three associates and approached Hoffman’s residence in an effort to enforce what he believed was his right to detain the man he accused of assaulting him. As the group entered the property, Gardiner contacted the police to inform them of his intentions. Unfortunately for Gardiner, this attempt at self-justice spiraled out of control.

Details of the Confrontation

Upon arrival at Hoffman’s home, Gardiner confronted him directly, declaring him under arrest and presenting a makeshift “warrant.” Hoffman, reportedly familiar with both Gardiner and one of his accomplices, responded by demanding they leave his property. As tensions escalated, physical altercations ensued.

Gardiner’s confrontational approach included aggressive language, urging Hoffman to “sit down and go to jail like the little bitch you are.” The situation escalated further when Gardiner physically restrained Hoffman, leading to a struggle that resulted in injuries for both men. Hoffman suffered significant facial injuries, including lacerations and a fracture, while Gardiner and his associates left the scene only after Hoffman retaliated with a spatula.

Legal Repercussions

The aftermath of this incident led Gardiner and Michael Davies, one of his accomplices, to face legal consequences. Both men were charged with common assault and wilful trespass. During the sentencing hearing, conducted by Judge Stephen O’Driscoll, the court emphasized the unlawful nature of Gardiner’s actions.

Judge O’Driscoll described Gardiner’s attempt at a citizen’s arrest as “extremely unusual,” pointing out that he had no legal authority to perform such an action. The judge further noted that Gardiner’s belief in his right to apprehend Hoffman was misguided.

Gardiner received a sentence of two months’ community detention and nine months’ intensive supervision. Davies, who chose not to comment during the proceedings, was sentenced to 12 months of supervision. The court also acknowledged that another associate, James Dell, had previously faced charges of wilful trespass related to the incident.

This case serves as a cautionary tale, highlighting the risks associated with taking the law into one’s own hands, and the importance of relying on legal authorities to handle criminal matters.
