John Kellermeier, 38, of Scott Street, pleaded guilty in the Warrnambool Magistrates Court this week to nine charges relating to two days in September last year.

His offending began the day after being served with an intervention order, with Kellermeier turning up the following day at the home of those who had taken out the order against him.

An argument ensued with one of the occupants, with Kellermeier eventually leaving while issuing the threat “don’t forget to lock the doors”, leaving the victim distraught and fearful, the court heard.

The next day — September 11, 2013 — Kellermeier went to Cobden Primary School where he followed two girls around.

“This caused the girls to become worried and one of the girls turned to see how close the accused was behind her,” the police prosecutor told the court.

When one of the girls tripped over, Kellermeier raised his middle finger at the girls, made a threatening gesture and then fled the scene.

He later turned up at the Cobden hall where the primary school was staging a play.

Kellermeier was brandishing a steering lock, which he started banging on seats and the floor and waving around while seated inside the hall, the court heard.

He then began making threats and swearing profusely and loudly despite a large number of children sitting just five metres from him. 

A teacher eventually asked Kellermeier to leave.

Kellermeier then turned up at a nearby business which he threatened to burn down before spitting at a victim and causing damage to a car and a hot water service.

He was arrested later that day and placed in psychiatric treatment.

Nine charges arose from the incidents, including two counts of intentionally damaging property and single counts of threatening to destroy property, being drunk in public, unlawful assault, behaving in an offensive manner in a public place, using threatening language in a public place, breaching an intervention order and theft from a shop.

The court heard his mental state was a factor in the offending.

Kellermeier was sentenced to four months in prison.
