A man accused of firing a shotgun into a Griffith unit has been refused bail for the second time in a week.

Jayke Fleury, 27, appeared in the ACT Magistrates Court on Thursday charged with shooting a 12-gauge shotgun through the lounge room window of a Stuart Flats unit last week.

Magistrate Peter Morrison refused the accused man's bail application, saying he posed a risk to the complainant.

The court heard the shooting came four hours after a brawl between Fluery and the complainant in Deakin.

Both men sustained head injuries and Fleury threatened to shoot the complainant during the fight, according to a statement of facts tendered in court.

The complainant then went home to his Griffith flat, where he was asleep on a mattress on his lounge room floor when he was woken, about 2am, by a loud bang.

He opened his eyes and saw a "bright yellow flash and dust and powder in the air".

The round went through the window and into an inside wall, passing over the sleeping man.

The complainant was not injured and sought refuge in the hallway until police arrived.

The court heard the fight had been sparked by bad blood between the men over a family issue.

The long-term girlfriend of Fleury is the cousin of an ex-partner of the complainant.

But that relationship had soured.

Police swooped on Fleury's Deakin home about 3pm the same day, allegedly seizing a 12-gauge shotgun stored in the roof cavity, four shotgun rounds and three mature cannabis plants.

A police informant told the court the firearm is currently undergoing forensic and ballistic analysis.

Fleury is due to reappear in court next month.
