Video shared on social media shows an unarmed man walking up behind one of the suspected gunmen and grabbing him around the neck.

The civilian wrestles and disarms the gunman, who falls to the ground before walking away.

New South Wales Premier Chris Menz praised the man's actions.

NPR has not independently verified the man's identity.

But several reports say that the man is 43-year-old Ahmed Al Ahmed, a fruit shop owner.
