A passerby seen wrestling and disarming one of the gunmen who opened fire at a crowd at Bondi Beach is being heralded as a hero as footage of the brave act circulates online.
At least 15 innocent people died and many more were left injured after a father and son took aim at a crowd gathered for a Hannukah celebration at the beach just before 7pm yesterday.
One of the gunmen is in police custody while the other was killed.
Multiple videos posted to social media show two gunmen standing on a footbridge connecting Campbell Parade to the Bondi Pavilion, firing shots into a crowd.
The men could be seen firing guns as people screamed and sprinted for cover.
In an act that may have prevented more deaths, one of the gunmen was disarmed and prevented from firing further shots into the crowd.
Footage of the altercation shows a bystander - named in Australian media as 43-year-old father of two Ahmed el Ahmed - dressed in a white shirt and black pants, crouching behind a parked car in the Campbell Parade car park.
He then sneaks up behind the gunman before wrestling the firearm from his grip in the potentially fatal tussle.
The altercation sends the man who had previously held the gun staggering to the ground before he gets up and walks towards the carpark bridge overpass where another shooter was continuing to fire.
The video appears to be taken by an occupant filming from an apartment overlooking the scene.
Ahmed's cousin told 7News that he had undergone surgery after later being shot in the upper arm and hand.
It's been reported he ran a fruit business.
