Officers were called to the airport about 1.30pm on Sunday following multiple reports of gunshots.

“CCTV has been reviewed and at this time the person in custody is believed to be the only person responsible for this incident,” a police spokesman said in a statement.

“The Canberra Airport terminal was evacuated as a precaution and the situation at the airport is contained.”

Social media posts show police pinning down an apparent suspect.

No injuries were reported. However, witnesses said as many as three gunshots were fired near the check-in counters.

Images on social media show bullet holes in window panels of the terminal.

The airport was evacuated shortly after the shooting incident, with parts of the terminal locked down.

Passengers who had boarded planes were stuck on the tarmac for hours before being allowed to disembark.

The airport was reopened to passengers just before 5pm. Flights in and out of Canberra remain grounded.

Police said there was no ongoing threat to the community or to other passengers.

Videos shared online have shown police interviewing evacuated passengers outside the terminal.
