Law enforcement source identifies Bondi gunman as Sydney man Naveed Akram

One of the alleged shooters in the deadly attacks at Bondi Beach in Sydney was Naveed Akram, a man from the city's south-west, according to a senior law enforcement official.

The official, speaking on condition of anonymity, said Mr Akram's home in the suburb of Bonnyrigg was being raided by police on Sunday evening.

Fifteen innocent people were killed and dozens injured in the attacks hours earlier on a crowd attending the first night of Hanukkah, the eight-day Jewish festival celebrating the endurance of the faith.

One of two gunmen was also killed at the scene, while the other was injured and taken into custody in a critical condition, NSW Police said.

It is not clear to the ABC at this stage which one is Mr Akram.

NSW Police Commissioner Mal Lanyon suggested that one of the shooters was known to authorities but "the person that we know has very, very little knowledge to the police".  

"So he's not someone that we would have automatically been looking at at this time," he said.
