A major police operation had swung into action as officers descended on a Avis Avenue address at about 5.40pm. A shot had been fired through the window of a neighbouring home.

Police, including Armed Offenders Squads and the Eagle helicopter, were deployed.

Just before 8.30pm, a man came out of the first house with a firearm and was shot by police.

He has been taken to hospital in a critical condition.

A cordon will remain in place overnight and a scene examination will begin tomorrow.

More to come.
