Michael Wayne Clark, 32, said these words before chasing one man and striking another outside a Tuggeranong tattoo parlour in February.

The ACT Magistrates Court heard Clark – a senior Nomads bikie – had gone to the Monash tattoo parlour to see one of the victims about a disputed $5000 debt over a business transaction.

However, he became upset when the man refused to speak to him and lashed out.

Clark pleaded guilty before in court on Thursday to two counts of common assault.

Court documents said Clark had worked with one of the victim’s at now-closed Tattoo Culture.

In October 2016, Tattoo Culture closed permanently after a fire, causing a dispute between Clark and the victim about outstanding debts each party claimed they were owed.

CCTV footage of the incident, played in court, shows a group of men speaking on the footpath.

Clark arrives and enquires about their well-being, saying: "How are you going fellas?"

The group greet him and Clark asks: "What's happening?"

One man responds by saying: "Just eating a lollipop."

Clark then tells the victim he wants to speak with him, but the man refused, before the offender tells the man he will bash him if he doesn’t come and talk.

Clark: "Come here and talk to me. I just bashed your mate … look I've got his blood all over me. I'm more than to bash all of yous right now if you want. Come on."

Clark then lunges at the victim, who retreats, before striking the second victim in the head as he passes by.

Clark then turns and walks back towards his car and drove away.

At sentence on Thursday, defence barrister Jack Pappas likened the incident to a "storm in a teacup".

Mr Pappas said the incident had not been premeditated and only became heated after the victim refused to speak to Clark.

"The heat of the moment got the better of his good judgment," Mr Pappas said.

"This was a business dispute about monies outstanding that simply boiled over for a minute on that afternoon.

"Unfortunately, it’s a fact of life that not everyone will go to the small claims court."

Mr Pappas said his client had left the scene as soon as his "good judgment returned".

Prosecutor Anthony Williamson said the offence had a number of aggravating features, including threats, and the victim had a pre-existing injury.

Magistrate Karen Fryar, in handing down sentence, said she accepted that not every person sought court assistance to resolve business disputes.

However, Ms Fryar said that did not entitle Clark to take the law into his own hands.

"I can't make a finding that there was an element of premeditation but you're old enough to know how to control yourself," she said.

The magistrate accepted that Clark's advance on one victim would have put him in fear for his safety, while the second victim had only received a "glancing blow" on the way past.

She assessed the offence as low-to-mid range.

Ms Fryar sentenced Clark to a one-year good behaviour order and a $1000 fine.

The magistrate also placed a non-association order on Clark not to be near the victim or the tattoo parlour.
