Hamid Reza Karimi faced the ACT Magistrates Court charged with aggravated burglary with intent to cause harm and intentionally wound.

His coaccused Amir Abbas Nikbin, 19, also appeared on a charge of aggravated burglary with intent to cause harm.

The court heard the alleged assault occurred after the defendants discovered Nikbin’s sister was dating a known womaniser.

Police said the accused were concerned for the woman’s honour and went to the boyfriend’s Gungahlin home to confront him.

But he was not home and then men instead became involved in an argument with his housemate.

Karimi then allegedly bashed the man on the head with a kitchen knife before threatening witnesses.

The prosecution opposed bail, arguing the accused could interfere with witnesses and fail to appear at future hearings.

The prosecution also said Karimi posed a risk of committing further offences as the conflict had not been resolved.

A police informant said both men had only arrived in Australia this year and had limited links to the territory.

But defence lawyers argued Karimi and Nikbin had no criminal records, voluntarily handed themselves into police, and were willing to abide by strict bail conditions, including surrendering their passports and reporting to police daily.

Magistrate Bernadette Boss granted the pair bail.

Karimi and Nikbin will reappear later this month.
