Extraordinary video has emerged from the Bondi Beach terror attack showing a hero creeping up behind one of the gunmen and successfully wrestling his rifle off him.

At least two gunmen opened fire at Bondi Beach on Sunday evening where a Jewish holiday celebration was underway, in what is believed to have been a mass casualty event.

Video obtained by the Daily Mail shows a heroic man creeping up behind one of the gunmen via the carpark at the north end of the beach, and then wrestling him to the ground.

The hero then waves a rifle in the man’s face.

The gunman then walks away and the hero drops the rifle.

Police have confirmed two gunmen are in custody.

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 into the crowd as people screamed and sprinted for cover.

A number of people could be seen lying injured and unmoving on the grass at North Bondi.

Others were being loaded into ambulances on stretches while onlookers attempted to provide support.

Separate footage showed officers standing guard over a hunting rifle lying on the ground with an exclusion zone in place.

NSW Police confirmed two people had been taken into custody shortly before 8pm.

‘Two people are in police custody at Bondi Beach; however, the police operation is ongoing and we continue to urge people to avoid the area,’ the force said in a statement.

Police are still advising the public to avoid the scene.

Those on the ground have reported panic, confusion and disbelief as chaos continues to unfold with emergency services on the scene.

Many members of the Jewish community had assembled for a Hanukkah celebration in the area earlier in the evening.

NSW Premier Chris Minns described the reports and images coming from the scene as ‘deeply distressing’.

A spokesperson for Anthony Albanese said the prime minister was aware of the incident.

‘We are aware of an active security situation in Bondi,’ the spokesperson said.

‘We urge people in the vicinity to follow information from NSW Police.’
