Hi, I am an international student in Melbourne. Yesterday, one of my housemates argued with another one. During the argument, one of them in extreme rage took out his knife and hurt the others. 3 people got injured and 1 girl who even was not involved in the argument was badly hurt with her leg. She had been sent to the hospital for a emergent surgery. The raging one has been arrested by the police. However we just got that he had been released by the police in yesterday evening. Everyone in the room got a bit worried about this. Is it normal for him to be released so soon under criminal law, and what possible punishment is waiting for him? He is also an international student. Would he be sent back to his country? Thank you!
