On Friday afternoon, 30-year-old Hassan Khalif Shire Ali pulled up on Bourke Street in his four-wheel drive, which caught fire.
Shire Ali stabbed three men, with a man in his 60s dying at the scene and two others recovering in Royal Melbourne Hospital.
Police and civilians tried to subdue Shire Ali before police shot him in the chest. He died in hospital.
In developments on Saturday, The Herald Sun reports that police have raided a house in Werribee, believed to be the home of the attacker’s father.
Chief Commissioner Graham Ashton says the Somalian-born Shire Ali was the brother of a man arrested by police late last year in relation to committing acts in preparation for a terrorist attack.
His brother Ali Khalif Shire Ali faced court earlier this year in Melbourne accused of plotting a terrorist attack on New Year’s Eve.
Speaking on the Today Show on Saturday morning, he said Shire Ali’s car contained gas cylinders and it is believed he intended to cause an explosion.
