The brother of the accused Bourke Street killer has spoken for the first time, saying "no one could've predicted" the alleged attack which killed five people and injured dozens.

Angelo Gargasoulas was allegedly stabbed by brother Dimitrious on the morning of January 20. Later that afternoon, Dimitrious was arrested after allegedly driving his car through the Melbourne CBD and mowing down dozens of pedestrians. Five people, including a three-month-old baby boy and a 10-year-old girl, were killed in the Bourke Street incident.

Dimitrious Gargasoulas has been charged with five counts of murder.

The Age reported Angelo was still in hospital recovering from stab wounds when he posted a message to his Facebook page on Sunday. Angelo was admitted to The Alfred hospital in a critical condition but he said "it's all looking good".
