One of the men allegedly involved in Sunday's terrorist attack at the famous Bondi Beach in Australia has been tentatively identified by investigators as Naveed Akram.

The hunting club’s president, Vanja Kuet, told Serbian news outlet Blic Online that Naveed had attended the association about five years ago.

Before Sajid Akram was granted a gun licence, the domestic intelligence agency ASIO had warned NSW Police that his son, Naveed Akram, had been associating with Islamic extremists.

The 24-year-old, along with his father Sajid Akram, shot dead 15 people and injured at least 40 others in an attack at Bondi Beach.

Verena, the mother of Naveed Akram, a suspect in the Bondi Beach Hanukkah shooting in Sydney, was shocked to hear of her son's involvement in the shooting, saying he was a "good boy" and the type of son every mother would want.

At least one of the gunmen who killed 15 people in Sunday's Bondi Beach terrorist attack was known to authorities as a follower of a notorious Sydney pro-Islamic State cleric, the ABC can reveal.

Major media outlets across the globe have praised the bravery of 43-year-old hero Ahmed al Ahmed, who tackled terrorist Sjid Akram during his murderous rampage.

A Sydney man of Pakistani origin says he's been targeted with abuse by people falsely accusing him of being one of the gunmen in the Bondi Beach shooting.
