Alleged Canberra airport shooter detained

The 63-year-old from NSW will remain in custody until the case returns to court on September 5.

Ammoun's legal aid solicitor Tamzin Lee moved to prohibit the ABC from reporting on the case but the application was opposed by the prosecution and the judge.

"I am satisfied this is an open court and the ABC has a right to report on such matters ... unless there is a good reason to suppress the proceedings," magistrate Robert Cook told the court. 

Police allege Ammoun fired a number of shots from a handgun into windows about 1.25pm on Sunday before being apprehended by federal police stationed at the airport. 

No one was injured during the incident but the airport was evacuated and remained closed for about three hours.

Ammoun has been charged with discharging a firearm at a building, unlawful possession of a firearm and discharging a firearm near a person causing alarm.

He is yet to enter a plea.
