Police in the Australian state of Victoria said Friday that a critically injured man had been arrested and a "small number" of people injured by stab wounds after an "incident" in the state capital, Melbourne.
They said they had initially responded to a report of a car on fire. No one else was being sought in connection with the incident at this stage, they said.
Local media showed footage of a man stabbing at police officers before being shot.
