A man is in custody while Canberra airport has been evacuated after what is understood to have been a shooting.
Early reports indicate gunshots were fired outside the security checkpoint in the main terminal building about 3.30pm NZ time.
The Australian Federal Police have since arrested one person, with social media footage showing a man being handcuffed and detained by officers.
Officers have also recovered a firearm.
"CCTV has been reviewed and at this time the person in custody is believed to be the only person responsible for this incident," ACT Policing said in a statement.
